Ovulation after pos OPK

Sam

Hey guys so I got a positive opk around 5 AM yesterday morning. I had sex at 3 AM this morning and we may have sex again in a few hours tonight, but I’m nervous it’s too late to have any chance at conceiving. I’ve heard that you ovulate 12-24 hours after the surge but everywhere i’ve looked online said 24-36. i know the egg can live up to 24 hours....

i’m just wondering if it’s possible or if anyone has gotten pregnant this late after a positive opk?
