if your OPK was positive on the 24th then you probably didn't O until about the 26th or so (those tests detect the hormone that sets off the release of the egg which usually takes a day or two after you get a positive) so the sperm would be about 2-3 days old by then, there is definitely still a change you could get pregnant from that, since they can live up to 5 days but id definitely say its a lower chance, typically the best time to have sex If youre TTC would be within 24 hours AFTER you get that positive OPK..

I say your chances are best when you bd BEFORE your OPK turns positive. You def have a good chance this cycle. Best wishes.

Since opk's detect your LH surge, you can ovulate any where from 12 - 36 hrs after getting a positive opk. As stated by another member sperm can live for several days in your cervix, so the few days prior to ovulation are considered prime days when ttc, so there is a chance you caught the egg. Good luck hon, I hope this turns out the way you want it to.

The surge means the initial time the test turns out positive. For me, I get a positive result a few days in a row. BUt from what I have read, its the day you receive the first positive result that indicates ovulation is 24-36 hours away. so you may have missed the initial surge form not testing. YOu could have tested positive (like me) for 3 days in a row, and already have ovulated well before having sex. there's just no way to know.
So I guess I'm saying you proabbly don't have a higher chance.. but who knows! good luck.
