Pregnancy anxiety

My boyfriend and I tried to have sex a couple of weeks ago, it was unprotected but it hurt so much that it didn’t go all the way in. He didn’t finish In me, there was no pre cum (at least I don’t think so) and I’m also on birth control. I’ve been having pregnancy anxiety ever since, I’m probably over thinking this whole thing but I can’t stop stressing about it, my period is in 7 days but I’m so anxious and stressing myself out.. I need advice.
