How to Calculate the Date You Got Pregnant and Conceived a Baby

Determine the father of your child by knowing the date of conception. Here's how to calculate the date you got pregnant.

If you have become pregnant through artificial means such as in vitro fertilization, you may or may not know the exact date you conceived a child. In normal intercourse you can predict the date with 100% surety if you remember the day on which you indulged in sexual intercourse and if you have done it only once during the entire period. In such cases, the date of conception is the date you had sexual intercourse. For all other instances it would be rather an estimate. How doctors estimate the date of conception is somewhat in the same manner. That’s why you have the due date with you once the doctor knows that you are pregnant.

Last Menstrual Cycle

The last menstrual cycle also assists in determining the date of conception. Most dates and time concerned with pregnancy are stuck with the last day of your menstrual cycle. For instance, date to find out gestational age, the conception date, baby's due date and so on. When you visit the doctor for the first appointment for pregnancy, he or she will for the date of your last period, that is, the day of commencement of bleeding. To evaluate your due date, they just count 40 weeks from then on. So if you are already in say, your fourth or fifth month through your pregnancy and don’t remember the start date of your last menstrual period, the just refer to a calendar and count 40 weeks and reach the date. That will be the due date for you.

Conception Date

From the date on which your last period began add 2 weeks from then on. Every woman goes through her own pattern of menstrual cycle. That’s why the process of ovulation, when the eggs are released from the ovary, also differs in women. In general, however, ovulation takes place anytime from around 11-21 days from the beginning of your cycle. The calculation has been stated by the American Pregnancy Association. As soon as the ovary releases the egg, it should be fertilized in a span of 24 hours or it dies. As the lifespan of a sperm inside the woman’s body is just about 2-3 days, this implies that the "window" for t5he woman for getting pregnant is only a few days prior to ovulation to a day post ovulation, states Baby Center. Few women have menstrual cycle more regularly compared to others, and there are women who are able to state the exact time of their ovulation. In such cases, the woman will be able to narrow down the date of conception a bit more. If you keep track of when you've indulged in a sexual intercourse, it may be easy to pinpoint the correct date.
