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!
A. If you have a 28 day cycle, you will generally ovulate on day 14. If you have a 35 day cycle, you will ovulate on day 21. In other words, the first part of the cycle (prior to ovulation) is where the variation is. You will, as a rule, begin your period 14 days after you ovulate, if the egg is not fertilized.
