Help meee

So my boyfriend and I were having sex about a week ago and when he put it in it was just excruciating pain in one little spot inside my vagina and then it started bleeding. i’m still bleeding rn a week later and i think it may be my period?? but it’s weird that it started right after that happened especially cos i just finished my period a week beforehand BUT i DID just start birth control.

so later that night i tried sussing it out and there was a little bump which hurt a lottt. it went away a few days later but it’s still a bit sore when i try having sex.

i googled it and there’s so many things that pop up and it’s scaring me to death!!!

please give me an explanation!
