Ovulation Calculator

Being aware of the days you are most likely to be fertile would be helpful if you are planning to conceive. The usual menstrual cycle lasts for 28 days but each woman is different. The fertile window is that period of about 6 days during each menstrual cycle when a woman can get pregnant. We have brought this calculator to help you check on which days you are most likely to be fertile.

This Ovulation Calendar calculator estimates the window when you’ll ovulate by counting back 14 days from the day of your next estimated period. In case of a cycle longer than 28 days, the next period should start 28 days from day 1 of the previous period. Your fertile window includes the day of ovulation and the five days before, however, note that you’re much more likely to get pregnant during the last 3 days of this tenure.

Our pregnancy ovulation calculator provides you with an estimated date you’re most likely to be fertile over the coming months. So, get prepared and mark your calendar!

Signs of ovulation:

  • Rising body temperature
  • Tenderness of the breasts
  • Mild cramps in the abdomen
  • Mild spotting
  • Increased sex drive
  • Elevated sense of smell
  • Bloating

So do use this calendar to plan your family. Of course, our experts are always there to help you in case you need any clarification.


Ovulation calculator is not always 100% accurate. But if you have a regular menstrual cycle, it can be quite useful.

Yes, your ovulation date can change each month. Ovulation doesn’t always happen on the exact same day in a given month. It usually varies by day or more on either side of the expected date.

Ovulation normally happens halfway through a menstruation cycle, but it varies from person to person. A new menstrual cycle starts on the first day of a period.

You can calculate your ovulation by entering the first day of your last period and the length of your menstrual cycle. The Ovulation Calculator will then provide you with the approximate date of ovulation along with the days that you will be the most fertile.
