... second pack (this second time around). I take it around the same time everyday, but the day before I took it a couple hours late. (Still on the same day) probably 3 hours later than when I should have. But the next day I had unprotected sex. It wasn't all the much, he put it in about 4 times, but didn't finish in me. I then took my birthcontrol on time right after.. Could I be pregnant? Do I need to take a plan b pill? It's been about 28 hours since we've had sex
