Understanding Your Menstrual Cycle

The menstrual cycle typically lasts between 21 and 35 days, with ovulation usually occurring about 14 days before your next expected period. However, this can vary.

Calculating Ovulation with a Regular Cycle

If you have a regular cycle, calculating ovulation is straightforward:

  1. Determine your cycle length: Count the days from the first day of your period to the day before your next period starts.
  2. Subtract 14 days: Ovulation typically occurs about 14 days *before* your next period.

So, if your cycle is 28 days, you'd typically ovulate around day 14. If your cycle is longer, say 32 days, ovulation would be around day 18.

For example, if you started your period on the 12th and have a 28-day cycle, ovulation would likely occur around the 26th of the month (12 + 14 = 26). Our ovulation calculator can help you easily figure this out, so you don't have to count!

The Fertile Window

Your fertile window includes the day of ovulation and the five days before it. Sperm can survive in the reproductive tract for up to five days, so having intercourse during this window increases your chances of conception.

What if My Cycle is Irregular?

Irregular cycles make it harder to predict ovulation. In this case, consider these methods:

  • Basal Body Temperature (BBT) Tracking: Monitor your temperature every morning before getting out of bed. A slight rise indicates ovulation.
  • Ovulation Predictor Kits (OPKs): These kits detect the surge of luteinizing hormone (LH) in your urine, which happens 24-36 hours before ovulation.
  • Cervical Mucus Monitoring: Check your cervical mucus daily. As you approach ovulation, it becomes clear, slippery, and stretchy, like raw egg whites.

If you are having trouble determining when you are ovulating, please consult with a healthcare professional.
