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!
It's possible to have a positive OPK without ovulating. The OPK does not test for ovulation, but for the LH hormone, which usually precedes ovulation and which stimulates the egg to ovulate. A positive OPK without ovulation can happen under the following circumstances: 1. LUFS (luteinized unruptured follicle sydrome) where there is a surge in LH but no egg is released.
