Although pregnancy is an exciting time in a woman's life, it can also be quite overwhelming. Especially if you are pregnant for the first time, it is normal to feel uncertain and anxious.

Amidst the chaos, learning about your due date, date of conception, and different screening schedules can help you feel in control.

It can make you feel confident about your ability to handle the practicalities of pregnancy.

The Pregnancy Calculator helps you do just that.

This calculator tells you all you need to know about your due date, along with recommendations for prenatal visits that you can follow to stay on top of the changes during your pregnancy.

How to Calculate Pregnancy Due Date and Pregnancy Schedule Using the Pregnancy Calculator?

The Pregnancy Calculator is an easy-to-use tool designed to help pregnant women estimate their due dates.

Along with the pregnancy due date, the calculator generates a complete pregnancy schedule that you can follow till the due date.

Here are the methods that you can use to get an estimate for your pregnancy due date:

• Last Period
• Conception Date
• IVF (Vitro Fertilization)
• Ultrasound

You can choose any of these methods to estimate the due date and more information about your pregnancy.

Once you enter the required details, the calculator will give you complete information about the pregnancy.

Here is the output that you get with the pregnancy calculator:

• Estimated Due Date
• Gestational Age
• Date of Conception
• First Fetal Heart Tones by Doppler Test
• End of First Trimester
• Blood Draw for Serum Integrated Screening
• Nuchal Translucency (NT) Ultrasound
• Quad Marker Screening
• Best Time for Cervical Length Evaluation
• Best Time for Routine Anatomy Ultrasound
• 2 Hours Glucose Intolerance Test (OGTT)
• Anti-D Prophylaxis
• Antepartum Fetal Surveillance
• Screening for Vaginal and Rectal GBS Colonization
• Potential Elective Delivery Schedule for Singletons

How Does the Pregnancy Calculator Figure Out the Pregnancy Schedule?

Studies show that the timespan for a normal pregnancy can be anywhere between 38 to 42 weeks.

And since pregnancy has a certain level of uncertainty associated with it, the due date can change because of certain complications.

But still, it is possible to get a close estimation for the due date. This is where the pregnancy calculator comes in.

This calculator uses various methods to estimate the expected due date. These include using the date of the last menstrual cycle, the conception date, IVF date, and the ultrasound date.

The pregnancy calculator allows you to use any of the above methods to find the EDD (Estimated Due Date).

You get details such as the EDD, the Conception Date, and additional useful information that can help take the pressure off your shoulders during pregnancy.

Last Period

You can use your Last Menstrual Period (LMP) date to find the estimated delivery date. If you know your LMP date, you can count about 280 to 300 days from there to get an idea about your EDD.

Now, if you don’t want to do the calculation manually yourself, the Pregnancy Calculator can help you do the same thing.

And not just that, the pregnancy calculator also tells you about the estimated dates for different tests and screenings based on your input LMP date.

Conception Date

The LMP date method is only recommended for women who have regular menstrual cycles.

If you don’t have regular LMPs, using the last period date won't give you the best possible results.

Alternatively, the conception date can also help you figure out the EDD. If you know your conception date, you can use that to get an idea about your due date.

It is a reliable method that works quite well. After the conception, the pregnancy duration can be anywhere between 266 to 280 days. So, if you know your conception date, you can get your EDD based on the average pregnancy duration.

The pregnancy Calculator uses the conception date to give you an idea about the pregnancy due date and suggests the complete pregnancy schedule.

IVF

IVF stands for In Vitro Fertilization. It is an assisted reproductive technology that has proven to be quite groundbreaking in medical sciences.

This technology works by using medicine and surgical procedures to help the sperm with egg fertilization. Once the egg is fertilized, it gets attached to the lining of the uterus.

According to the CDCs 2018 Fertility Clinic Success Rate Report, about 456 reporting clinics in the US performed a total of 306,197* ART cycles.

ACCORDING TO THE SAME REPORT, the ART cycles resulted in about 73,831 live births and 81,478 live-born infants.

If you know your IVF transfer date, you can add it to the Pregnancy Calculator, and it will use that to give you an estimation for your due date.

Ultrasound

When you go for your prenatal appointment, Ultrasound is one of the things that can help medical professionals figure out your due date.

If you get an early ultrasound, it gives you the best possible idea about the due date.

So, if you don’t know your conception date and last menstrual cycle, then going for an ultrasound scan is your next best bet.

There are various clues in the Ultrasound that can help medical professionals pinpoint the expected due date.

Now, if you know the date of your Ultrasound, you can add it to the Pregnancy Calculator. The calculator will give you the due date based on the date when you had the Ultrasound.

Pregnancy Guide – Everything You Need to Know

Pregnancy can be scary; there is no doubt about it. Especially if it is your first time, you are bound to feel anxious and overwhelmed.

But pregnancy doesn’t have to feel that way for you.

To make the pregnancy experience a little less overwhelming, we are going to walk you through the signs & stages of pregnancy so that you can better prepare yourself for the future.

Symptoms Of Pregnancy

A pregnancy test is the only way to figure out whether you are pregnant or not.

If you haven’t taken the pregnancy test yet and you are not sure whether you should go through with it or not, we suggest you learn about the common pregnancy symptoms.

When you know the pregnancy symptoms, it makes it easier for you to decide to take the pregnancy test.

Here are the most common pregnancy symptoms that you need to watch out for:

• Missed Period
• Swollen Breasts
• Increased Urination
• Nausea
• Fatigue
• Mood Swings
• Bloating
• Nasal Congestion
• Cramps
• Food Aversions
• Constipation

The above symptoms are the most common ones that pregnant women experience. Although these symptoms are common during pregnancy, you need to take the pregnancy test as soon as possible.

It is always better to seek professional assistance than to follow blind assumptions. So, if you suspect that you might be pregnant, you should go to the doctor at once to get an accurate assessment of the situation.

What Are the Different Pregnancy Stages?

Pregnancy can last anywhere between 38 to about 40 or 42 weeks. The duration of pregnancy can be divided into three different stages known as Trimesters.

Health specialists use this division to figure out the best possible treatment at each stage of the pregnancy.

Each stage in the pregnancy has different symptoms associated with it.

So, the division of pregnancy stages makes it easier for health specialists to take better care of their patients, as per the symptoms that they exhibit.

• First Trimester

The first three months of the pregnancy are known as the First Trimester. The body undergoes massive changes during the first trimester.

At this stage, the hormonal changes increase, and they start having an impact on the entire organ system in your body.

Here are some of the most common symptoms that are associated with the first trimester:

• Tiredness
• Morning sickness
• Cravings
• Constipation
• Mood swings
• Heartburn
• Weight gain
• Swollen breasts

• Second Trimester

The second trimester can be between 13 to 28 weeks. At this stage, the baby's body will start to form, so the abdomen of the pregnant woman is bound to expand.

Once the second trimester is about to complete, the pregnant woman might start feeling their baby's movement.

Below are some of the symptoms for the second trimester:

• Aches in the abdomen, back, and groin
• Stretch marks on the breasts
• Patches of dark skins on the cheeks, forehead, nose, or around lips
• Carpel tunnel syndrome
• Itchy palms
• Swollen ankles, fingers, and face

• Third Trimester

The third trimester starts from week 29 and lasts till the delivery. The symptoms for the third trimester are almost the same ones as the patient might feel during the 2^nd trimester.

Here are some common symptoms associated with the third trimester:

• Shortness of breath
• Heartburn
• Swollen fingers, ankles, or face
• Hemorrhoids
• The belly button may stick out
• Difficulty with sleeping
• Contractions

What Do “Terms” Mean in Pregnancy?

The complete duration of pregnancy is also known as a “full term”. It starts from the first day of your LMP.

Here is a brief overview of the terms in pregnancy:

Early Term – The gestation age between 37 to 38 weeks and 6-7 days is the earlier term.

Full Term – The gestation age between 39 to 40 weeks and 6-7 days is referred to as the full term.

Late-Term – The gestation age between 41 to 42 weeks and 6-7 days is called the Late-Term.

Post Term – The gestation age longer than 42 is referred to as the post-term.

Week by Week Pregnancy Calendar

If you want to feel in control during the pregnancy period, you need to know everything that goes inside of you during an average full term of the pregnancy.

We have created this week-by-week pregnancy calendar for you that you can use to keep track of the different developmental stages during your pregnancy.

This way, you’ll be able to know at all times what stage of pregnancy you are in and what to expect for the future.

Weeks 1 & 2:

The pregnancy timeline starts from the starting date of your last trimester. This is the time from where you need to track the weeks in the pregnancy.

During the first two weeks of the pregnancy, the follicles on your ovaries start forming. The strands then get released during your ovulation.

Week 3:

When week three starts, the egg is released and then fertilized by the sperm.

As soon as the process of fertilization starts, the chromosome helps determine the baby's gender, eye & hair color, and other characteristics.

But these changes don’t become prominent until much later. So, you might have to wait for a few weeks to see these changes via Ultrasound.

Week 4:

In the 4^th week, the baby gets implanted in your uterine lining and forms a tiny fetal pole.

During the 4^th week, the pregnancy symptoms start becoming prominent. These symptoms include tender breasts and a little bit of pressure around the abdomen.

Week 5:

In the 5^th week, the embryo of your baby is going to have about three layers. These include the ectoderm layer, the mesoderm layer, and the endoderm layer.

As the baby’s body grows, the ectoderm layer turns into the skin and the nervous system of the baby.

The mesoderm layer creates the bones, the reproductive system, and the muscles of the baby.

The endoderm layer forms the lungs, the mucous membrane, and the intestine. 

Week 6:

At week 6, you’d be able to detect the heartbeat of your baby with an ultrasound.

The heartbeat is going to feel like a fast flicker, but it is going to be detectable. You should be able to see it yourself.

You can see the heartbeat live via Ultrasound. But the heartbeat is going to be quite faint at this stage. So, you might not be able to see it clearly.

Week 7:

At week 7, the structure of the baby’s face starts forming. The arms and legs also start getting a little bit of definition.

This is when the symptoms of pregnancy also start getting severe. But at this stage, the symptoms should be bearable in an average case with no medical complications.

Week 8:

At week 8, the embryo should’ve turned into a fetus. The weight of the fetus is generally less than 1/8 ounces.

The pregnancy symptoms during the 8^th week include fatigue, tender breasts, nausea, frequent urination, and difficulty with getting good sleep.

Week 9:

During the 9^th week, the heartbeat of the baby becomes more easily detectable.

The toes and fingers start sprouting, and the head looks more developed. Along with that, the brain also starts gaining its form, and the organs start working together.

Week 10:

By the 10^th week, the genitals of the baby begin to develop. At this stage, you can easily tell whether it is a boy or a girl.

The Ultrasound might not be able to pick up the gender just yet. It should become obvious in the next few weeks.

Week 11:

During week 11, the baby's weight reaches about 1/3 of an ounce, and they get about 2 inches long. This makes you feel a weird kind of pressure in the abdomen area.

The toughest period of the pregnancy starts at week 11. But with proper guidance and support, you can go through it with confidence.

Week 12

In the 12^th week, the baby gains more weight and weighs almost an ounce. The height also increases to 3 inches.

You feel almost the same symptoms that you think during the 11^th week.

Along with that, the baby’s vocal cords start to form, and the kidneys start becoming functional.

Week 13:

At week 13, the second trimester kicks in. Now that you have gone through 1 of 3 trimesters, you start becoming accustomed to the changes in your body.

Although the degree of discomfort increases, you get better at managing it.

During the 13^th week, the baby starts urinating in the amniotic fluid. The intestines of the baby also shift from the umbilical cord to the abdomen of the baby.

Research shows that during the 13^th week, the riskiest part of the pregnancy is over. Around this time, the chances for miscarriage are as slim as 1% to 5%.

But still, you are suggested to exercise utmost care from your end.

Week 14:

During the 14^th week of the pregnancy, the length of your baby from the crown to the rump is about three and a half inches. And they weigh about one and a half ounces.

You might feel a little bit of weight on your abdomen, but that is just an indication that your baby is growing.

Week 15:

At week 15, the bodily structure of the baby starts becoming more prominent. You can get a glimpse of it through an ultrasound.

Week 16:

During the 16^th week, the baby becomes a lot bigger and starts gaining more weight as well.

On average, a baby gets about 4 to 5 inches long from head to toe and weighs about 3 ounces.

During the same week, your baby might even start making very few motions with their mouth.

Week 17:

During week 17, you might start feeling heavy because of fat stores. But it is a natural mechanism that helps keep your baby warm and give them energy.

At this stage, the baby becomes five and a half inches long and weighs about 7 ounces. These are the growth stages where most of the structural development takes place for the baby.

Week 18:

The 18^th week is important for your baby as this is the time where the senses start developing.

The ears start forming, and their eyes also become more prominent. They might also begin to detect your voice and may even react to the light.

Week 19:

In the 19^th week, the vernix caseosa starts coating the body of the baby. This protects the skin of the baby from the harmful effects of the amniotic fluid.

Vernix Caseosa is a protective material that is kind of wax-like. This material protects the skin of the baby against wrinkles and stretches.

Week 20:

At the 20^th week, your baby should be able to hear your voice. The baby is going to weigh about 9 ounces at this point.

The height of the baby should be about 6 inches at this point. During this week, you might also start noticing a little bit of kicking in your womb.

Week 21:

In the 21^st week, your baby will have some fine hair, also known as lanugo. This hair covers their entire body.

During the 21^st week, your baby should be about seven and a half inches long from crown to rump. They should weigh almost a pound in this week.

Week 22:

During this week, you can see what looks like a proper form of a baby. The Ultrasound can easily pick it up, and you can see it in real-time yourself.

This is when you need to exercise a lot of care and watch out for the symptoms associated with the second trimester.

Week 23:

At week 23, the kicking inside of the womb will start becoming more intense. But you don’t need to worry about that because it is just your baby experimenting and adjusting to the surroundings.

Week 24:

During the 24^th week of the pregnancy, your baby should be almost one and a half pounds in weight, and they should be about a foot long.

At this week, the taste buds start forming, and their fingerprints complete as well.

Week 25:

At the 25^th week, the baby’s senses grow stronger and become more acute. Their startle reflex starts forming, and you might even begin to notice specific patterns of movement in them.

Although all of that happens subconsciously, it is enough to figure out the patterns of movement such as sleep and rest for the baby.

Week 26:

At the 26^th week, the baby becomes almost 13 inches from crown to rump. They weigh just about 2 pounds at this point.

During this week, the baby might recognize certain voices and react to certain patterns in a minor way. This is when the pregnant females start reaching the end of the second trimester.

Week 27:

In the 27^th week, the baby’s nervous system and lungs start becoming more powerful. This is the time where you can try keeping track of the movement of your baby.

If the movement follows a certain pattern, then everything should be fine. If you notice any kind of irregularities, then you should try consulting the doctor at once.

Week 28:

During the 28^th week, your baby’s brain becomes more developed. The amount of tissues in the body increases as well. This week can be the end of the second trimester for most women.

Week 29:

Your third trimester starts in the 29^th week. This is where the most difficult part of the pregnancy begins.

At this stage, your baby should weigh about 3 pounds, and they should be about 15½ to 16 inches from the crown to the rump.

During this week, you might also want to keep track of the symptoms for the 3^rd trimester. This will allow you to prepare yourself for what is coming mentally. 

Week 30:

This week, your baby should weigh about 3 pounds. During the 30^th week, the bone marrow of your baby starts collecting red blood cells.

It is a crucial stage of their development, and you need to be extremely careful with your movement and dietary habits at this point.

Week 31:

At the 31^st week, your baby should become about 15 to 17 inches from head to toe. The weight of the baby should be close to 4 pounds during this week.

During this week, the visual focus of your baby improves, and their reflexes start developing as well.

Week 32:

At this week, the nervous system of the baby starts reaching its peak stages of development. The nervous system becomes developed enough to regulate the body temperature of the baby.

Also, research shows that women can give birth after 32 weeks, and the child will have an excellent chance of survival (over 95%) with professional medical assistance.

Week 33:

At this stage, the sleeping patterns of your baby become more prominent. Their lungs also reach their full potential at that time.

Now that you are reaching the final stages of the pregnancy, you might start feeling severe symptoms.

Week 34:

At the 34^th week, your baby should be about 17 inches long. Their fingernails also develop and reach their fingertips at this point.

The vernix caseosa starts getting thicker too. The symptoms for this week would be the same as the previous ones that you feel in the 3^rd trimester. 

Week 35:

At this week, your baby's weight starts increasing at a huge pace, and the weight increases by about 12 ounces every week.

This is because the fat starts depositing around the shoulders of the baby. This contributes to the increased weight.

Week 36:

The weight of the baby gets to about 5 to 6 pounds this week. They become about 17 to 19 inches long.

Since your baby is a lot bigger now, they won’t have enough room to move around. So, it will be fine if you notice decreased kicks and overall movement.

You can consult your doctor for ways to assess fetal health. They will tell you about counting kicks and other ways to figure out how your baby is doing.

Week 37:

During the 37^th week, the baby continues gaining more weight. They will gain about half an ounce every week at this stage.

At this stage, the major organs of the baby are ready. The organs are prepared to work even outside of the womb as well.

Week 38:

At the 38^th week, your baby weighs more than 6 pounds, and they get over 18 inches long from head to toe.

The 3^rd trimester is almost at the end at this point. You might feel a lot of stress and pressure at this point. But you need to stay as calm as possible because stressing out will make things more difficult for you.

Week 39:

Once you are in the 39^th week of the pregnancy, it is considered the full term.

And now, the only thing that's left is for you to wait to get into labor. It can happen right at this time or can take one or more weeks.

There is no way of figuring out the exact time when it is going to happen. 

Week 40:

At the 40^th week, your baby should be ready to leave your womb and come into the world.

Experts say that babies born at the 40^th week can weigh between 6-9 pounds. Also, the baby is going to be between 19 to 21 inches long at this stage.

The Week by Week Calendar that we have given here is not definitive. Things can go a little bit different for you at the end of your pregnancy.

So, if you deliver a few days earlier or before your due date, you shouldn’t worry about that.

This is because research shows that only about 4-5% of the babies are born at the exact due date as the doctor gives.

Although it is useful to learn about the estimated due date, taking it as the final word won’t be a good idea.

Pregnancy Management Tips

Pregnancy is a journey that can feel quite long and arduous. But if you know how to take care of yourself properly during this time, and you follow your doctor's instructions, then you manage it effectively.

Here are some basic pregnancy tips that can be quite helpful for you along with the way

• Don't Be Careless With Medication.

You need to exercise extra care when taking any kind of mediation during pregnancy.

You should never take anything that is not prescribed to you by your doctor.

FDA has divided the drugs into different categories, including A, B, C, D, and X.

The drugs from category A are helpful for the fetus and have no side effects for the mother. On the other hand, the drugs belonging to the X category can cause severe fatal risks.

You need to be aware of all these medications to prevent potential health issues. You should always consult your doctor before taking any kind of medication during the pregnancy.

• Weight Management

Weight gain is inevitable during pregnancy. But the percentage can still vary from person to person.

Also, the weight of a person directly impacts the development of the baby and the overall pregnancy experience.

If the weight gain during pregnancy is insufficient or is excessive, both conditions can hurt the health of the baby.

According to a CDC report on weight gain during pregnancy, you need to define your weight management goals and try to meet them to avoid complications during pregnancy and labor.

Here are the weight management goals for women pregnant with one baby:

• If you are underweight (BMI less than 18.5), then you should try to gain about 28-40 pounds.
• If you have a normal weight (BMI 18.5-24.9), your goal should be to gain 25-30 pounds during the pregnancy.
• If you are overweight BMI(25-29.9), you should try to gain about 15-25 pounds.
• If you are obese (BMI equal to or more than 30), you should try to gain between 11-20 pounds.

We suggest you consult your doctor for the ideal weight gain goals if you are pregnant with twins, triplets, or more.

• Exercise

Studies show that aerobic exercises can help a lot during pregnancy. These exercises help maintain physical fitness and can even reduce the risk of a C-section.

But you need to be careful with the exercise because you don’t want to put your body under unnecessary pressure.

You can consult your doctor and ask them about the exercises that they recommend.

If you have symptoms such as vaginal bleeding, shortness of breath, dizziness, headache, swelling, etc., you should consult your doctor before getting into any kind of exercise.

All in all, exercise is a great way of keeping yourself physically healthy during pregnancy and can even make the process relatively bearable for you.

• Regular Prenatal Visits

Regular prenatal visits are important during pregnancy. By visiting your doctor regularly, you can stay updated with your health condition.

You need to make sure that you don’t miss any of the doctor’s appointments during pregnancy. Regular prenatal visits will help you catch potential health problems and complications during pregnancy.

When you are pregnant, your body undergoes massive changes throughout the pregnancy period.

The changes in the physical condition often induce emotional irregularities which can cause you to experience mood swings.

Amidst the chaos, regular prenatal appointments give you peace of mind that you are on the right track. This makes you more confident as you go through your pregnancy journey.
