I have a bit of a history w my periods. I'm 21. I'm 5'4'' and 180 lbs. So I'm a little overweight. LOL. Well ever since high school my periods have been very finicky. Depending on stress and what other girls I hung around depended on if I would have a regular period or not. But I think that's normal. October 2007 I was pregnant and I had a miscarraige in December 2007. Over the past year I've had sharp pains in my abdomen... like in my uterus and ovary area. I went to my normal pap and they said they found pre-cancerous cells but that they weren't serious enough to do anything about and that they'd watch it. I haven't had the money to go back. LOL. The pains have only gotten worse and more frequent. I have been unemployed the past few months and live with my boyfriend so I'm not really around girls... my periods have been starting around the same time the past 4-5 months. Last month I bled 3 different times though. Accompanied by the stabbing feeling. Now this month I am a wk late for my period. Nothing has changed. I'm nowhere near stressed so I don't know why it could be messed up. My boyfriend and I do have unprotected sex every now and then as bad as that is. I've taken 2 ept's and they've both come up negative. I don't know what's wrong. Does anyone have a clue??? Thank you.
