Help me??

I had sex with my boyfriend for the first time and he didn’t have a condom. He didn’t cum in me but I know I could still get pregnant, thoughts? Also, after that he was fingering me and I started bleeding a lot. I didn’t notice until he said something. He saw it and said something so I immediately went to the bathroom to see what was going on, it didn’t and still doesn’t hurt but what could have happened?

Edit: I already said I know precum exists, I’m not trying to get judged, I just want help.. it was unexpected and it was my first time
