Not sure If I could be pregnant or not

Hello all, I'm 16 and me and my boyfriend has sexual intercourse the about 6 days ago, but he didn't ejaculate inside of me, he took it out before, but there's always a chance that I could be pregnant, and we're kind of scared. I've been spotting since, but the weird thing is that I started bleeding in small amounts since an hour or two after we concieved, and it's been happening whenever I urinate, and I'm not sure if this is pregnancy sign or maybe just irritation. I think it's irritation, but would it last 7 days? It's only when I use the restroom, and it's been everyday for the past week. Not sure what this means but could someone help me out?

If your boyfriend didnt come inside you then your not pregnant. Are you do for a period anytime soon i spot b4 my periods come.? Thats not a sign your pregnant take it from me a mother of two its just a irritation

You could be. Pre-Ejaculate (the stuff that comes out before full ejaculation) can contain sperm.
