IVF and FET Due Date Calculator

Even if you have a regular menstrual cycle, ovulation doesn’t always happen on the same day. So while someone with a typical 28-day cycle might ovulate around day 14, it can happen earlier or later. This makes due dates more of an estimate rather than an exact prediction.
We are aware of how it feels to become a parent, and your anticipation of knowing when your little one makes their grand entrance into the world! Plus, knowing your due date is important for your healthcare providers to keep tabs on your baby’s growth and development. They can also keep an eye out for any potential risks or complications that may arise during your pregnancy.

On an average, pregnancy lasts for about 40 weeks or 280 days. When it comes to calculating the due date for natural conception, healthcare providers often rely on the first day of the last menstrual period rather than the date of conception.

Even if you have a regular menstrual cycle, ovulation doesn’t always happen on the same day. So while someone with a typical 28-day cycle might ovulate around day 14, it can happen earlier or later. This makes due dates more of an estimate rather than an exact prediction.

With an In–Vitro Fertilisation (IVF) pregnancy, it is easier to determine the date  when you conceived.

To use our due date calculator IVF, 

• Simply enter the date of your egg retrieval or embryo transfer, in the “Date of Transfer” field. 
• Enter the type of IVF you had, out of the given options in the “Type of Transfer” field.

Based on the information provided by you, our calculator will calculate and give you your estimated due date.

It is important to keep in mind that even with IVF, due dates are still only estimates. Factors such as the growth rate of the embryo, changes in implantation time, and individual differences in pregnancy length can all affect the actual date of delivery.

Additionally, if you have undergone a frozen embryo transfer (FET), the estimated due date with Fet Due Date Calculator may be less accurate due to the fact that the embryos may have been frozen for an extended period of time before transfer. In these cases, your healthcare provider may adjust your due date based on additional ultrasound measurements or other indicators of gestational age.
