Pregnancy Due Date Calculator
Methods to calculate the IVF due date There are several methods to calculate the due date for an IVF (in vitro fertilization) pregnancy, including: Blastocyst transfer: The due date is calculated based on the date of the embryo transfer. Ovarian stimulation: The due date is estimated by counting from the day of ovulation induction, taking into account the typical time it takes for implantation to occur. Frozen embryo transfer: The due date is estimated based on the date of the frozen embryo transfer and the developmental stage of the embryos at the time they were frozen. Donor egg: The due date is calculated based on the date of the egg retrieval or embryo transfer, or on the date of the donor's last menstrual period if it's known. It's important to note that while these methods can provide an estimate, they are not always accurate, and the due date may be adjusted later in the pregnancy. An ultrasound is usually the most accurate method of determining a due date.
