Pelvic cramp/pressure after sex

Sunny

Hey lovelies! I need some advice. I’ve been having pains in my pelvic floor, I had a quickie with my mans last night & im getting my period soon so that might explain the discomfort.

I’m std & sti free as well as I know I’m not pregnant. But it literally feels like if I move the wrong way, a nine is gonna fall out of my vagina (exaggeration).
