A woman with a sonogram photoModern technology and fertility treatments have helped countless people experience the joys of parenthood. In vitro fertilization (IVF) is one of the most popular fertility procedures, helping address male, female, and mixed factor infertility.

Many patients who come to our Lubbock fertility center wonder if their due date can be calculated after undergoing IVF. We'd like to explore these issues below, helping you understand the nature of IVF and the issue of gestational age.

Is It Possible to Determine Your IVF Due Date?


There are a number of ways to calculate IVF due dates. This will give you a general idea of when you will give birth to your child following IVF treatment. These calculators take into account a number of different factors while also noting some of the basics when it comes to pregnancy and childbirth.

Calculating IVF date helps give patients peace of mind, and gives them a sense of what to expect in the weeks to come. This sort of pre-planning can be very helpful for ensuring a general sense of wellness.

Pregnancy Due Dates: The Basics

Generally, the average gestational age for a pregnancy is 40 weeks from a woman's last menstrual cycle. This is just an estimate, however. A perfectly child can be born within a 30-day window of that 40 week period. In fact, many healthy, full-term babies are born between 37 weeks and 42 weeks.

If your baby is delivered late or a little early, this is not a sign of a birth defect or other issue. There are many factors that go into these averages.

How IVF Due Dates Are Calculated

IVF due date calculators tend to rely on various dates in order to estimate the gestational age. This includes the following:

  • The first day of a woman's last menstrual cycle
  • The day a woman ovulated
  • The day a woman's eggs were harvested
  • The day a woman underwent embryo transfer

Additional information may be taken into account for an IVF pregnancy, which can alter the due date or provide additional info regarding your pregnancy. This may include some of these topics:

  • Calculated due dates for multiple births (i.e., twins, triplets)
  • Dates for each trimester
  • Dates for prenatal testing

Is an Estimated Due Date Always Accurate?

While the due date is a precise window of time, it's no guarantee that you will deliver your child on that date. Only 10 percent of women deliver their child on their calculated due date.

As noted above, missing your due date does not mean that your child will be born unhealthy. It's normal to be a bit early or late. The calculated due date should be considered a helpful framework for understanding your pregnancy and the development of your child.

Working with Your Fertility Doctor

Since factors can change there is so much to consider when it comes to the health of your child, it's important that you work closely with your fertility doctor as well as your OB/GYN. They can offer you guidance throughout your pregnancy, and note various factors that may impact your due date.
