Not all the methods described above are the same in terms of accuracy, notes Dr. It takes the date of your ultrasound, subtracts the number of weeks at which your ultrasound is done and then adds 280.

IVF day 5 transfer: If your embryo was transferred to your uterus after five days of embryo growth, this method calculates your estimated due date based on 261 days from your date of transfer.

IVF day 3 transfer: If your embryo was transferred to your uterus after three days of embryo growth, this method calculates your estimated due date based on 263 days from your date of transfer.

If your pregnancy is the result of a successful in-vitro fertilization (IVF) procedure-in which eggs are extracted and fertilized with sperm, with the resulting embryo later transferred to the uterus-you can calculate your estimated due date based on the timeline of the procedure. It’s “often incorrectly estimated due to date of intercourse, which can be several days off from actual date of conception based on the sperm’s ability to survive for five days in the reproductive tract,” she says. Now, Kelly Culwell, M.D., an obstetrician-gynecologist and Forbes Health Advisory Board member, notes that the date of conception isn’t always a reliable method for determining your estimated due date. This method calculates your due date based on the date of conception by assuming a gestation period of 38 weeks (or 266 days) from the date of conception. Due Date Calculator: When Is Your Baby Due?
