This means ACTUALLY ovulating. So when you get that first positive OPK, you're typically 1-2 days before O happens and that is why we do things the way that we do - by having sex at that point in time, you hit the exact time you're going to have good chances of conception.
Anyone saying they had sex 2-3 days before a positive OPK and conceived from that either a) got insanely lucky (sex 4 days before O is 1 in 1000 chance of conception, 5 days before O is 1 in 10,000) b) was not testing correctly with OPK and didn't get their positive on the strip till very late in the surge, so the time from pos to ovulation was very very small or else they'd even already ovulated by the time they detected the surge c) had sex later on after they THOUGHT they'd ovulated and conceived from the later attempt or d) is lying/misspeaking to try to get attention or to fit in with some method of swaying they wanted to try even tho it didn't work out (I know it sounds crazy but people do this a shocking amount - either give some insane story about an impossible conception that simply cannot be true, or else stretch the truth to fit in with what a swaying site is telling them)
Most people online do not know what they're talking about with OPK. The apps are worse than nothing and are terribly misleading, giving lots of people incorrect info. Don't drive yourself crazy reading these things, come to me and get accurate information about OPK!
