It is very helpful to know how long your menstrual cycle lasts. This will help you understand when you are most likely to ovulate. If you don’t know how long your cycle is, start keeping track of it over the next few months. For example, if the length of your cycles for the past three months was 28 days, 29 days and 30 days, you would add those numbers together and divide them by 3. You would find the average length of your cycle to be 29 days.

Most women ovulate near the middle of their menstrual cycle. Doctors generally agree that ovulation occurs 13 to 14 days before your period starts. To see an example of this, look at the calendar above. If you count backwards thirteen to fourteen days from the 30th, you will see that the fertile period occurs around the 16th and 17th.

It is important to remember to count 13 to 14 days backward from the start of your period to determine the time you are most likely to ovulate.

Determining your cycle length

The first thing you need to do is determine the length of your menstrual cycle. Your complete menstrual cycle is the number of days from the first day of your period (the first day your bleeding starts) to the day just before your period starts again.

In the calendar shown, your period started on the 1st and your next period started on the 30th. This means that your cycle length was 29 days. Again, your cycle length is determined by counting the number of days including the first day of bleeding, to the last day of your cycle, just before the bleeding starts again.
