Hi, I having sex with my bf and he realized that the condom slipped off and hang on me after we done. He said he come in me but there's some left in the condom (our second sex that night), he said that he feel like he come a lot in me, and he's quite worry right now since we are 18.i take the postinor 2 about 60 hours after and second tab 12 hour later.I just get some side effect such as headcache, abdominal pain for short period and not yet get bleeding. My period started from 9 april and end in 13 april, we having sex at 25 april.Am I safe?
