IVF Pregnancy Calculator

Tsong Law Group

About this app

The IVF Pregnancy Calculator is a useful tracker for intended parents, surrogates, and fertility professionals. IVF pregnancies are tracked two ways: gestational weeks, counted from the last menstrual cycle, and weeks post embryo transfer, counted from the transfer date. Converting between the two isn't always easy, but this app does it for you, you just provide the date and the age of the embryo. In surrogacy contracts, both numbers can matter: a certain week mark when a baby is considered premature or full term, and when certain contract benefits kick in. You can save your results and add them to your calendar. You can even keep track of multiple pregnancies at a time.

Use the app to:
- calculate gestational age from embryo transfer details
- estimate due date from IVF transfer timing
- work backward from an estimated due date
- save results on your device for later reference
- share saved results through text
- save important dates to your calendar
- and just for fun, see the size of the fetus in comparison with a fruit

The IVF Pregnancy Calculator stores saved results and preferences locally on your device. Calendar access is optional and only used if you choose to save a date to your calendar. No data is shared with a third party without your permission.
