ok, so I am hoping the chance is slim but I had sex twice with my boyfriend in one night and he used a different condom each time. Afterwards he took the condom off and we snuggled naked. I've heard it is possible for sperm to travel outside into the vagina. F.Y.I. We cuddled right away after the act. I have been off BC for several months and I am probably paranoid since the condom didn't break but I took plan B a little over 48hrs. Then I restarted my BC that same night I took plan B(around 4hours later). Should I be worried or am I overthinking this?
