Pregnancy scare!

My boyfriend and I rarely use condoms as it feels better without. Anyway we were going at it and he accidentally came in me, like the full load. I'm really scared. I'm waiting till Valentine's Day as I'm supposed to get my period that day (huge bummer) but I'm still really scared. I'm on anti depressants and my gp said if I ever think I might be pregnant stop taking them but I'm not going to as I'm not supposed to just stop taking them as it's dangerous. I'm supposed to be going on the pill soon but yeah. Sorry this is a rant/asking for advice?? 😰💕
