So, last week I slept over at my boyfriend's place. We had unprotected sex (I know we are supposed to use a condom but we hate it so stop judging) for those two days. We went one round on Thursday and then two rounds on Friday. I am on the pill and I know that there is a very small chance of pregnancy. I take it PERFECTLY (right on the dot) so I should be fine, right? I'm a worrier so I just want to be sure. I also ended my period last Wednesday.
