Ovulation count back: In a regularly cycling female ovulation usually occurs 14 days prior to your period if you don't get pregnant. Any abnormal period should be followed by a pregnancy test. So if you have a 28 day cycle 28 -14=14 so sex should be a few days before Day 14 To a few days after. If 30 day cycles then sex surrounding day 16 and if a 32 day cycle sex surrounding Day 18.
