During the IVF process, many expectant mothers are often confused about how to calculate their due date. For women who conceive naturally, the due date is typically calculated from the first day of their last menstrual period, extending over 280 days (approximately 40 weeks), resulting in a due date about ten months later. However, the method for calculating the due date in IVF differs from natural conception since it depends on the embryo transfer date, which is especially important for women undergoing IVF.

 

What is a Due Date?

 

A due date refers to the estimated date from the beginning of pregnancy to the expected birth of the baby. For expectant mothers, understanding their due date is crucial because many prenatal tests and fetal monitoring are scheduled based on gestational age. Conducting these tests too early or too late can affect both the baby's and mother's health, and even influence decisions regarding when to induce labor or perform a cesarean section.

 

How is the Due Date Calculated in IVF?

 

For women undergoing IVF treatment, due to the use of ovulation induction drugs and variations in menstrual cycles, the due date cannot be calculated in the same way as in natural conception. The scientific method for calculating the due date is as follows: if a day 5 blastocyst is transferred, the due date is calculated by subtracting 19 days from the embryo transfer date, which serves as the hypothetical last menstrual period. If a day 3 embryo is transferred, subtract 17 days from the transfer date to determine the starting point.

 

Dr. Nathan Zhang, the founder of IVF USA and a U.S.-trained medical doctor, emphasizes that in the U.S., blastocyst transfer is more commonly chosen because embryo labs can cultivate embryos to the blastocyst stage by day 5. Additionally, the embryos undergo PGS genetic screening to ensure that only healthy embryos are transferred, which significantly improves the chances of successful pregnancy and reduces the risk of miscarriage and fetal arrest.

 

Adjusting the Due Date with Ultrasound Scans

 

In addition to calculating the due date based on the embryo transfer date, expectant mothers' due dates can also be adjusted via ultrasound scans. Ultrasound scans can assess the development of the baby and further refine the due date, helping doctors evaluate the babys growth. However, the due date is only an estimate, and statistics show that only about 5% of women deliver on their due date. The actual birth time of the baby is influenced by various factors, including the uterine environment, the babys development, and the mothers health condition. Therefore, expectant mothers should not be overly fixated on the exact due date.

 

Preparing for Delivery

 

Typically, once you reach 37 weeks of pregnancy, you should begin preparing for delivery, as the baby could arrive at any time. This is particularly important for mothers undergoing IVF, as in addition to gestational age, it is essential to consider the babys weight and overall development to assess maturity. By staying relaxed and following a natural course, you can be in the best possible condition to welcome your baby.
