Okay so here's the deal. I had been on the pill for almost four years, I took a couple months off from it and went back on it last month. This month I forgot to pick up my prescription and haven't been on it. My boyfriend and I had sex two days ago, we used a condom. But the thing is that after he finished as he was pulling out the condom slipped off. He said he was almost all the way out, only the last little bit of the condom was still inside me. Nothing came out and nothing got on me that I know of. I'm supposed to get my period this week (I think!) if not I'm definitely getting it next week. I'm really worried I could be pregnant. I haven't had any tell all signs (it was only two day ago) but I'm stressing which I know can delay periods. Should I be worried? Please help!
