Can you tell me how to know my ovulation period and when to meet with my husband my period started yesterday?

Ovulation prediction: Most women ovulate around day 14. (Day 1 is the first day of your period) If you want to be more precise, you can do ovulation predictor kit testing. You don't need a prescription just go to the pharmacy. Start testing your urine around day 12. When the test is positive, you know you will ovulate in the next 12-48 hours; so that night and the next are the best time for you and hubby.
