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!
I count the day after I think I ovulated as 1DPO. I think I ovulated on the 15th, so I count the 16th as 1DPO. I've only been checking CM this cycle, no OPK.
