What Is Ovulation?

Learn more about Ovulation!

Ovulation is when a mature egg is released from the ovary, pushed down the fallopian tube, and is available to be fertilized.

Approximately every month an egg will mature within one of your ovaries.

As it reaches maturity, the egg is released by the ovary where it enters the fallopian tube to make its way towards waiting sperm and the uterus.

The lining of the uterus has thickened to prepare for the fertilized egg. If no conception occurs, the uterine lining as well as blood will be shed. The shedding of an unfertilized egg and the uterine wall is the time of menstruation.

What is Conception?

Conception is the time after you ovulate and sperm meets the egg! Sperm can live 3-5 days. So you might have sex on say 10th, but might not ovulate till 13th, so conception would be on or just after 13th.

The only way to have an accurate idea of when you conceived is to know the date that you ovulated during the cycle in which you got pregnant. You can determine the date of ovulation with around 96% accuracy by measuring your cervical mucus according the the Creighton Model (http://www.creightonmodel.com/).

Your egg will live less then 48 hours if not fertilized, so once you determine the ovulation date, you can be confident that you conceived within 48 hours. However, sperm can survive in your system for around 5 days.

If, for example, you had sex on August 1st, and ovulated on August 4th, it is possible to conceive on August 4th or 5th. If you ovulate on August 4th and have sex on August 5th, you may conceive on August 5th (+ a few hours into the 6th maybe). Calculating the due date based on menstruation is about a 2 weeks accurate because the number of days between menstruation and ovulation varies between a woman’s cycles.
