Due Date Calculator: Fertility 4+

The Due Date Calculator app is a fertility-specific pregnancy due date calculator designed primarily for physician use. The app calculates the pregnancy due date for women who have undergone fertility treatment including embryo transfer, IUI and egg retrieval. Due date information may also be calculated using the date of ovulation.

How to Use the Due Date Calculator app:

View the options in the dropdown menu under “Calculate Pregnancy By” header and make your selection. Next, using the “Select Date” menu, enter the appropriate date and press calculate. Results will indicate the date of the last menstrual period (LMP), estimated due date, gestational age of the baby and likely date of conception.

The Due Date Calculator app is appropriate for use in women with a history of infertility as well as those who conceived naturally. For the best results, use the most accurate data available.

If a baby was conceived by natural conception, the estimated due date is determined by the first day of the mother’s last normal menstrual period. If an ovulation kit was used to detect LH surge, the ovulation date should be used to determine the expected due date. Due dates can also be calculated using the embryo transfer date or date of insemination.

Pregnancy due dates are not precise, but rather an estimation of the day a woman might be expected to give birth. Most women deliver within a two week period before or after their anticipated due date.

For use with IVF, IUI, HCG Trigger, LH Surge, Embryo Transfer.
