Ovulation Tracker
Estimate Your Fertile Window and Ovulation Date Online
Use Apollo Hospitals' Ovulation Calculator to estimate when ovulation is likely to occur during your menstrual cycle. Knowing your fertile window can help if you are planning a pregnancy or simply wish to understand your reproductive health better.
The calculator uses details such as the first day of your last menstrual period (LMP) and your average cycle length to estimate your most fertile days and likely ovulation date.

Pregnancy is most likely to occur during the fertile window, which includes the days leading up to ovulation and the day of ovulation itself.
