I need help!!!! Pls!!!

This is kind of a dumb question but if you have sex and u hurt ur cervix or something and can it start up ur period? (Don’t judge too hard I really don’t know, and I’m just wondering because I’m kind of going through this) when should ur cervix or tissues heal by?

Backstory:

I had sex with my boyfriend 6 times in two days and we didn’t have sex since the first time I lost my virginity, three months ago. And my vagina has been messed up since. and when I have sex why do I keep getting weird reactions to my vagina? I had sex for the first time around three months ago and my period was a month late and then my period started after and my period did really stop till Tuesday for reals and now I’m bleeding again...because idk what.

Present day:

But anyways I’m sure but not 100% sure I’m not pregnant it’s only been 2 days since I had sex but every time we used a condom but everytime he didn’t cum in me but we had a lot of friction the last time (I don’t think I was producing enough lubricant) and the last three times he went in really deep in me and idk what happening to my body.

I’m not on the pill or anything... I need help! I’m 17 and have no idea what’s going on
