Question about most fertile day.

Sooo!! Yesterday the 11th was my most fertile day to get pregnant only thing was that our work schedules messed everything up! I got stuck at work until 9:30pm and he picked up hours to go into work at 11 .. By the time I got home it was 10:18 and he had to be out the door no later than 10:30 so we did have sex and I seen alot of "stuff" coming out of him like dripping but this was during sex while he was going in and out but he didn't ejaculate because we were going so slow and by the time I looked at the clock it was 10:36...so we had sex this morning ...my question is how many hours will my egg stay for? We had sex on the 10th too but it was early in the day I'm just hoping that I didn't miss my egg and that the sperm from the previous day was still strong ....
