For many women, calculating their due date is a fun and exciting part of the fertility process. It can be exciting to think that in just 9 months, you’ll be holding a baby. Tools such as an IVF due date calculator can help you to pinpoint your due date as well as important milestones. Calculating your IVF due date is much more accurate than estimating a natural conception date of birth. When you become pregnant through IVF you can calculate a precise due date for your baby. This is because you will know the exact date of your fresh embryo transfer or Frozen Embryo Transfer (FET).
