Precum doesn't contain sperm but I can't be 100% sure either

See me and my bf have been dating for a year or so, but but because I come from a religious family you know we don't get to hang out on our own much so basically I'm still a virgin or was one lol yesterday I was on my own and it was our only chance of making love and because it wasn't planned condoms weren't planned either we had sex..well Idk it hurt me badly he couldn't get in until like after 15 mins of trying I didn't bleed instantly but I did later anyways he didn't get to thrust in me much max five thrusts then id scream in pain and I have to say he was very gentle <3 and he'd stop when I ask it hurt twice first because of breaking my hymen and secondly when ever he thrusted a bit deep I felt like it was hitting somethin and I couldn't bear that pain so he had to stop he pulled out and came outside And this was 5 or 6 days after my period So to sum up unprotected sex after 5-6 days of my period and he didn't cum in side me nor did he thrust continuously. Am I pregnant? I'm 17 btw.. Thxx a lot I'm so scared plz help me I don't want any babies now :'(:'(:'(:'( I keep calming my self by saying he didn't cum in me and precum doesn't contain sperm but I can't be 100% sure either..
