Precum in flipped condom

So my boyfriend and I had sex yesterday and while he was putting on the condom on he put in on backwards and realised it immediately and flipped it correctly. My ovulation ended a day before. I'm scared of the pre-cum resulting in pregnancy. Although we had to adjust a few times before he actually was in me. And the condom wasn't sticky at all. He hadn't ejaculated 24 hours ago and did pee before sex. So there's no chance of sperm in the precum. Should I take an emergency pill? It's been over 24 hours.
