Ovulation Calculator

If you are trying to conceive finding out when you ovulate and your most fertile days can help you increase your chances of pregnancy.

You’re most likely to get pregnant if you have sex within a day or so of ovulation (releasing an egg from the ovary). This is usually about 14 days after the first day of your last period if your cycle is around 28 days long. An egg lives for about 12-24 hours after being released.

The Babypalooza ovulation calculator can help you discover the most fertile days of your menstrual cycle or your estimated fertility window.




Enter the date of the first day of your last menstrual period (LMP):

How long is your cycle between periods:

Start with the first day of one period and count right up to the day before the first day of your next period. Count the first day of bleeding or spotting as day one. The average cycle length is 28 days, but can range anywhere from 20 to 45 days.


How can you tell if you are ovulating?

  • Rise in basal body temperature, typically 1/2 to 1 degree, measured by a thermometer
  • Higher levels of luteinizing hormone (LH), measured on a home ovulation kit
  • Cervical mucus, or vaginal discharge, may appear clearer, thinner, and stretchy, like raw egg whites
  • Breast tenderness
  • Bloating
  • Light spotting
  • Slight pain or cramping in your side
