Estimate your pregnancy timeline with our IVF Due Date Calculator.
Our IVF due date calculation is based on the date of your embryo transfer. Here's a general guide:
While IVF conception is precisely timed, your baby's actual arrival may vary. Studies and community experiences show that only about 4% of babies are born on their exact due date. Your IVF due date provides a valuable estimate, but be prepared for a window around this date.
This depends on the clinic and protocol, but typically, a 3-day transfer is considered to be at 2 weeks and 3 days of gestation, and a 5-day transfer at 2 weeks and 5 days of gestation, counting from a theoretical Last Menstrual Period (LMP).
Immediately after a 5-day transfer, you are often considered to be about 2 weeks and 5 days pregnant in gestational terms. Your clinic will provide the most accurate dating.
IVF due date calculation is often considered more precise because the date of conception and embryo development is known exactly, unlike in natural conception where the exact timing of fertilization may be unclear.
Yes, your healthcare provider might adjust your due date based on early ultrasound measurements, especially if there's a significant difference from the calculated date.
Unlike natural conception where due dates are often estimated from the Last Menstrual Period (LMP), conception date, or early ultrasound, IVF due dates are calculated from the known date of embryo transfer, offering a more precise starting point.
