Calculate precisely when you're due, how many weeks along you are, your conception date, and more with the most precise babyMed due date calculator developed by a real MD and ObGyn doctor. Calculating an accurate due date is an important first step in pregnancy. The calculation of the estimated due date (EDD) is based on the day of the date of ovulation and fertilization. The EDD can be calculated by adding 266 days to the day of ovulation/fertilization. There is no way of knowing the exact date of conception unless a woman tracks her cycle and has unprotected intercourse only once per cycle. However, you can make an estimated guess!
The conception calculator will give you an estimated date of the probable time when conception occurred. The due date calculator will then calculate the exact date the baby will be due, as well as other important events such as the date of implantation, when the baby will start moving and dates for important tests like amniocentesis, ultrasound, or glucose screen.
