Now that you know how far along you are, it might be helpful to know that pregnancies are often referred to in weeks and trimesters. Take a look at this pregnancy timeline for a breakdown of the weeks, months, and trimesters of pregnancy:

Here are some of the things you can expect in each trimester of pregnancy:

First trimester : You might notice some early signs of pregnancy, such as morning sickness and food cravings. Your provider will be able to confirm your pregnancy and set up your prenatal visits to make sure you and your baby stay healthy and safe.

Second trimester : This trimester is often referred to as the honeymoon phase of pregnancy. You may feel as if you have some extra energy to get things done, like baby-proofing your home, going to prenatal classes, and doing some gentle pregnancy exercise.

If you aren’t already, this may also be a good time to start doing Kegel exercises to strengthen your pelvic floor muscles. You can do these simple muscle clenches anywhere, and they’re beneficial not only during pregnancy and labor, but afterwards as well.

Third trimester : You’re nearly there! As you get closer to the birth of your baby, you’ll want to get prepared by making sure you have all the right baby gear. But remember to take the opportunity to slow down and rest whenever you can.

Is 26 Weeks Considered 7 Months Pregnant

How many months is 26 weeks pregnant? At 26 weeks, youre in the sixth month of your pregnancy 6 months, 2 weeks, to be exact. With 14 weeks to go till your due date, youre still in the second trimester, but by the end of week 27 youll be heading into the third trimester and your final stretch of pregnancy.

How To Calculate Due Date With Ivf And Fet

When you undergo IVF and a fresh embryo transfer , youll add 38 weeks, or 266 days, to the date of the egg retrieval to get your due date, explains Luis Murrain, DO, an OB-GYN and cofounder and partner physician with Dreams Fertility in Palm Springs, California. That calculation holds true if youre using your own eggs or if youre using donor eggs or a donor embryo.

If you choose to calculate from the date of the embryo transfer, however, youll need to do a little more math. Youll add 266 days but then subtract three days for a Day 3 transfer or subtract five days for a Day 5 transfer. With a frozen embryo, its calculated the same way.

This is because the embryo is frozen in time, Dr. Ryniec says. So even if you transfer the embryo next month, next year, or in 10 years, it is still a Day 3 or a Day 5 embryo, so you can still add 263 or 261 days from transfer day.

Working Out Your Due Date

1-minute read

Once you have confirmed that you are pregnant, you will want to find out when your baby is due to arrive. The average pregnancy is calculated at 282 days from the first day of your last menstrual period.

However babies rarely keep to an exact timetable, so a full-term pregnancy can be anywhere between 37 and 42 weeks. A baby born before 37 weeks is considered to be premature and anything past 42 weeks is considered overdue.

Due dates are usually calculated on your last period instead of the date of conception because of a number of reasons.

• Although the average woman ovulates approximately 2 weeks after her period, the exact time is not always known.
• Once an egg has been released, it can remain fertile for up to 24 hours.
• Sperm can last for up to 5 days after intercourse to fertilise an egg.

If your periods are irregular or you are unsure of the date, an ultrasound will help determine the development of the embryo and your due date. Ultrasound scans can be done at any stage of pregnancy after the first 6 weeks. The best timing for an ultrasound to determine the due date is between 8 weeks and 13 weeks 6 days.

You can use the Pregnancy, Birth and Baby due date calculator to work out when your baby is due.

Some doctors will refer to your due date as ‘expected date of confinement’ or EDC.

How To Calculate Weeks Of Pregnancy

Pregnancy is calculated based on your last menstrual period. Week one of your pregnancy will start on the first day of your LMP. Likewise, the following weeks are calculated. This may sound weird, but it helps in giving the exact date for timely medical care. Unless you had an assisted conception and knew when the fertilization took place, the LMP method is the only way to know the closest ovulation and conception dates.

The doctors can help you with the exact calculation of weeks and months of pregnancy through other ways.

How Accurate Are Due Dates

While due dates give you a good idea of when your baby may arrive, its unlikely your baby will be born on this exact date. In fact, only 4% of babies arrive on their due date1 most babies arrive within a week of their due date – around 90% of babies will arrive in the 2 weeks either before or after the predicted due date.

Fresh Vs Frozen Embryo Transfers

If youre going through IVF, heres what you might need to know about the difference between fresh and frozen embryo transfers. As you can probably surmise, one transfer involves freshly created embryos and the other involves embryos that were created at some time in the past and then frozen and stored.

Typically, a fresh embryo transfer occurs three or five days after egg retrieval for fertilization, according to the Society for Assisted Reproductive Technology . By contrast, a frozen embryo could be frozen for months, or even years, before being thawed out and then transferred into the uterus. Frozen embryo transfers are very common, according to SART, with some people choosing to use frozen embryos left over from a previous cycle.

One thing you wont need to worry about is whether or not your estimated due date will be affected by whether your embryo was freshly created or spent some time in the freezer. The due date should be the same whether you are transferring a fresh or a frozen embryo, Dr. Murrain says.

Calculate Using A Pregnancy Test With Weeks Indicator

All pregnancy tests are designed to detect the pregnancy hormone human chorionic gonadotropin in urine, but some pricier tests offer a weeks indicator that promises to tell how far along you are. Unfortunately, these tests are pretty vague, stating only one to two weeks, two to three weeks or three-plus weeks pregnant. In addition, the tests measure from implantation, not from your LMP. A test might say that youre one to two weeks pregnant but youre actually four weeks pregnant, according to standard pregnancy calculations.

Third Trimester: Week 27 Onward

As you continue to put on a few more pounds, your baby is growing fast, tooand developing new movements, such as opening and closing eyes, as well as kicking and stretching and grasping.

When you calculate your IVF pregnancy due date, you will learn how far along you are in your pregnancy, and what to expect from there.

Role Of Fundal Height

Your midwife or doctor may measure your fundal height at your pregnancy well-checks. The fundal height is the measurement in centimeters from your pubic bone to the top of your uterus. It should grow at a predictable rate as your pregnancy continues.

After 20 weeks, your fundal height in centimeters will typically be the same as the number of weeks you are pregnant. In other words, at 21 weeks pregnant, your fundal height should be around 21 centimeters .

Sometimes, the fundal height won’t match perfectly. Slight variations are normal, but if you are measuring much smaller or larger than expected, your primary care provider may want to investigate with another ultrasound.

While useful, the fundal height is not an accurate measurement of gestational age and would not affect the estimated due date in any way.

What If You Dont Know Your Lmp Or Your Periods Are Irregular

In the case where you do not know the exact date of your last menstrual period or if you have not had a regular menstrual cycle, the doctor estimates the foetal age through ultrasound imaging. Parameters like the crown-rump length and the foetal sac measurements give an idea about the rough age of the foetus. Based on the foetal age, the expected delivery date is given by the doctor.

What Is My Due Date

Your due date, also known as your estimated date of delivery, is the approximate date your labor might begin. Your estimated due date is commonly calculated by adding 280 days to the date of the first day of your last period, using Naegeles rule.1This may vary if you have irregular periods.

It’s worth noting that although predicted due dates are commonly calculated at 280 days, a baby is born on its predicted due date just 5% of the time.2 A 2020 study published in the International Journal of Obstetrics & Gynaecology suggests a number of factors that can influence the length of your pregnancy, including ethnicity, height, variations in the menstrual cycle, the timing of ovulation, parity and maternal weight. It is for this reason that calculations using Naegeles rule can be considered as an estimate and not a definitive date.3

Where Does 40 Weeks Come From

The most common way to calculate a due date is to set it at 40 weeks past the woman’s last menstrual period. This is known as Naegele’s Rule, after the German Obstetrician Franz Karl Naegele who published the method in 1806. He suggested taking the first day of the expectant mother’s last period, adding one year, subtracting three months, and adding seven days, although the science behind what he said isnt clear.

It is important to remember that your due date is not set in stone, but is in fact an estimate of when you might go into labour give or take 2 weeks!

Can My Due Date Change

During your prenatal checkups, your healthcare provider will monitor how far along you are. Don’t be surprised, though, if your provider gives you a slightly different due date than the one you calculated.

Also, most babies don’t arrive exactly on their due date. Every pregnancy is unique, and only a small percentage of babies are born right on time. Babies are typically born between weeks 38 and 42, and it’s totally normal for your baby to arrive any time during this window.

If your baby is born pre-term, your doctor will be able to advise you on any extra care your baby might need. On the other hand, if your baby isn’t born by the end of week 42, your doctor may suggest inducing the labor to bring on a vaginal birth, or he may discuss the option of a cesarean section with you.

If You Are In Your Fifth Week Of Pregnancy Why Are You Referred To As Four Weeks Pregnant

Sarah Owen, author of The Complete Guide To Pregnancy And Child Care, helps clear the confusion about pregnancy weeks by relating them to a babys age. When a baby is one year old, she completes the first 12 months of her life. Though she enters the second year, she is called one-year-old. Similarly, when you complete the first week of pregnancy, you are known to be one-week pregnant, even though you enter the second week.

A quick look to understand the terms and counting of pregnancy weeks:

• In your first week of pregnancy, you will be referred to as being zero weeks pregnant.
• In your second week of pregnancy, you will be referred to as being one week pregnant.
• In your third week of pregnancy, you will be referred to as being two weeks pregnant.

And so on.

It is for this reason that when you miss your first period, you are four weeks pregnant even though you are in your fifth week of pregnancy .

Which Trimester Am I In

There are three trimesters in pregnancy. Each trimester consists of three months.

The first trimester includes the first three months of pregnancy, or weeks 1-13.

The second trimester includes the next three months and weeks 14-27.

The third trimester includes the last three months and the weeks starting from week 28 until the delivery.

So, to know which trimester you are in, you just need to know which week you are in.

You may have heard about the fourth trimester. This is a way to talk about the newborn period since this is truly a new phase for both the baby and new mom.

How Do Doctors Calculate Pregnancy Week

Although the LMP method of due date calculation is widely accepted, doctors sometimes estimate the pregnancy week by alternate means to determine the actual foetal age. This is particularly useful for women who have been experiencing irregular periods and do not remember their last menstrual cycle date. One of the following two methods is followed to assess the age of the foetus.
