So my ex and I had sex on a friday. And I started my period the next day but I wasn't supposed to start till mon. It was horrible cramps. I was throwing up and couldn't hold anything not even water down. Also bad diarrhea Does this mean I'm pregnant? Then we had sex again Wednesday and he nutted but I'm on my period and I got light abdominal pain and back pain. Also shortness of breath. Am I pregnant or what's wrong?
