What is a pregnancy due date?

Calculation of the pregnancy due date is the single most important part of prenatal care. Everything in pregnancy depends on what your exact due date is and how many weeks along the pregnancy has come. Your pregnancy due date is calculated by adding 266 days (38 weeks) to your ovulation and fertilization date or 280 days to the first day of your last menstrual period (LMP). babyMed has the most precise pregnancy conception calculator. Find out why estimating the correct pregnancy due date is important.

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. 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.
