Me and my boyfriend were having rough sex doggy style last night and nothing hurt while we were doing it. But now like 15 hours later I’m having extremely bad lower back pain and pains in my uterus almost like period cramps but worse. I’m not exactly sure if that’s normal??? Has anyone experienced this. I’m not exactly sure if this is something I should go to a doctor for or let heal in it’s own. (Plus my period is like 3 weeks always so I should not be starting anytime soon)
