I had unprotected sex with no ejaculation on the 27th and on the 28th my period started. It caused me a lot of pain but that's not unusual for me. On the 30th my period had seemed to stop but around the middle of the day I suddenly started bleeding but it was bright red and loose. About two hours later it stopped. After it stopped I was still cramping and I'm still cramping and its now the 4th. I've also had diarrhea, dark almost black stool, back pain, and I'll get extremely tired out of nowhere but after a little while it will go away. Can someone please tell me what's going on?
Sounds unlikely but take a test to be sure.
How many times did you have unprotected sex in that month? If you had unprotected sex a few times you can get pregnant from precum. Sperm can live up to 7 days inside you. Maybe you got pregnant and maybe what your going through right now is a miscarriage. If I was you I would go see your doctor.
I only had unprotected sex once that was the first time.
