Posts: 2,427. Hi there, OPK detects LH Surge, which in most cases occurs 12-36 hours BEFORE ovulation....if you got your OPK at 8.45 am yesterday morning, you could expect to ovulate anywhere between yesterday evening to tonight!
Taking the âperfectât 28 day cycle as our example again, if your cycle lasts 28 days, you will ovulate approximately 14 after your period and 14 days before your next period. It gets a little tricky when your not on the âperfectâ 28 day cycle. For Instance, if your cycle last 31 days ovulation will occur about 17 days after your period and approximately 14 days before you start your next period.
