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!
Now moving on to how long does it take to ovulate; the general answer is that you start to ovulate about 14 days after the last day of your menstrual cycle. The exact time for every individual is determined by the individual luteal phase. Luteal phase is yet another time period in the womenâs calendar which lasts for about 12-16 days and determines that how long does it take to ovulate for you. Once you find out the length of your luteal phase, subtract the number of the days from the time period between your two menstrual cycles.
