Pinpoint your most fertile days by calculating your estimated ovulation date and fertile window based on your menstrual cycle.
Ovulation is the monthly process where a mature egg is released from an ovary. The egg then travels down the fallopian tube, where it can be fertilized. This period is the most fertile time in a woman's menstrual cycle. For most women, ovulation typically occurs about 14 days before the start of their next menstrual period.
Your "fertile window" includes the day of ovulation and the five days leading up to it. Sperm can survive in the female reproductive tract for up to five days, so intercourse during this window provides the highest chance of conception.
Limitations: This calculator provides an estimate. Individual cycle lengths can vary, and factors like stress or health changes can shift the timing of ovulation.
