Ovulation Calculator
Women's Health by checkit.health
When are you most fertile?
Ovulation usually happens about 14 days before your next period. Because sperm can survive several days, the fertile window spans roughly the five days before ovulation plus ovulation day itself.
How accurate is a calculator?
Calendar estimates assume a regular cycle. Cycles naturally vary, and stress, illness and travel can shift ovulation. For a clearer picture, track cycle length over a few months, or combine with ovulation tests and temperature tracking.
