Using Our Ovulation Calendar

Did you know that we have an awesome ovulation calendar on our website that will help you figure out when the best time to have sex for conception is?

It is pretty easy to use and you only need to have a couple of criteria in order to make it work well for you.

  • You need have a menstrual cycle that is between 21 and 35 days long.
  • It is helpful if your cycle is relatively “normal” meaning that it is typically the same number of days long each month.
  • You need to know when your last period started.

If you have a cycle that is shorter or longer than what is needed or have cycles that vary widely in numbers of day in your cycle, you may have a hormonal imbalance that you will have to address. Our fertility supplements are a good place to start. If you find that your cycle doesn’t have a substantial change after using the supplements for 3 months, you will need to go and see your doctor to see what the issue may be.

Figuring Out How Long Your Cycle Is

You need to be aware of the dates that your period has started for at least two months. The length of your menstrual cycle is the number of days from the first day of menstrual bleeding to the day before the following menstrual period starts. So, if in the first month, your period started on May 28th and the next month it started again on June 25th, you would have a 28 day cycle.

      The number of days you are bleeding doesn’t matter. The number of days in your cycle is counted from the first day of bleeding to the day before your next period starts. From April to May, you had a 30 day cycle. From May to June you had a 31 day cycle. To figure out when you will be most fertile, you can enter your information into our ovulation calendar
