A lot of women who are thinking about getting pregnant are also thinking about how to calculate ovulation. In case you have a regular cycle and you don’t have any health conditions that would affect your ability to conceive, calculating your ovulation isn’t as difficult as you might think at first.

The length of your cycle to calculate your ovulation

First of all you need to find out how long your menstrual is. The menstrual cycle consists of the period of time starting with the first day of your menstruation, and ending with the day before your next menstruation. In the majority of the cases this cycle varies between 28 and 30 days, and it varies from one woman to the other.

How To Calculate OvulationIf you would like to calculate your ovulation and you have a cycle that varies a lot from one time to the other, then you will have to find some other calculation methods because counting the days might not offer you a certain time period.


When you are thinking about how to calculate ovulation, it’s not enough to know the length of your cycle, but you also have to calculate. Count backwards two weeks from when your menstrual period is supposed to start.

When you have the date, you should plan to have intercourse three days earlier.

Naturally when you managed to calculate your ovulation you have to have intercourse on all of these days to make your chances of getting pregnant bigger. Another thing that you should remember is that in case the circumstances are suitable, sperm can survive for 5 days, so it’s not a must to have intercourse in those days. Nonetheless it shouldn’t be a problem.
