How can i know my fertile window with a 21 day cycle?
A doctor has provided 1 answer
Ovulation prediction: In order to pinpoint the fertile window, ovulation time needs to be known. For this you can use over the counter ovulation predictor kits (opk) to test the urine daily starting day 8 of cycle. Once a positive test is obtained, that means ovulation will happen within the next 24 hours. Intercourse is recommended day of positive result as well as next 2 days.
