Bleeding after intercourse?

Kat

So I'm sure this is TMI and I've done a bit of research but I'd like to reach out to this community and see if anyone else has experienced this before.

So I noticed a few weeks ago that after my bf and I had sex, it was a little red after I went to clean up. I assumed it was my period starting... It wasn't.

It happened again, only there was more blood and it was accompanied with cramps and lower back pain like I was on day 2 of shark week which is usually the worst day for me. We stopped having sex for a few days and tried again but I couldn't self lubricate.

I've sunken everything I have into funds for a recent death in the family otherwise I'd be consulting my gynecologist.

My mom thinks this could be a lack of estrogen or vaginal tear?
