The most common method of determining your due date for pregnancy is to add 40 weeks to the start of your previous menstrual cycle (LMP). And most healthcare professionals operate in this manner. Your menstrual cycle likely began approximately two weeks before you became pregnant if it is the typical duration (a 28-day period). This explains why 40 weeks instead of 38 weeks is the typical length of a pregnancy.This approach disregards the length of your actual menstrual cycle or the time you believe you may have given birth. But usually speaking, ovulation occurs in women two weeks following the beginning of their menstrual cycle. Additionally, women are more likely to remember the beginning of their last period than the day they ovulated.

You can determine your pregnancy due date based on your conception date if you happen to know the exact date you became pregnant, such as if you used an ovulation predictor kit or kept note of your ovulation symptoms. Simply enter your date and select that calculating technique from the pulldown menu above. Again, you don't always get pregnant on the day you have sex.
