I haven't had my period since October , I'm having period symptoms. I have been cramping today I'm experiencing a sharp pain in my chest. It feels like it's coming on but has not. I have been stressed. I want to go the doctor to see what it could be but I can't afford it. I hope I'm not pregnant , the guy that I'm talking to (my ex boyfriend) I tired to tell him that I might be pregnant and he told me If I am it's not his because he pulled out. He is the only one I been sleeping with. I think it is most likely stress because he has really been stressing me out. Last month.
