I've always had irregular periods. Sometimes i would go 4 or more years without having a period. I went to the doctor in April of 2008 and she prescribed me Provera. When I started taking it, I had a period. I took it for 2 weeks and a had a regular period for 3 months. During that time I had sex right after I went off my cycle. When August came around I didnt see my cycle so I thought I was pregnant. But I didn't show signs of a period or a pregnancy. Now its March and my last cycle was July 2008 and I'm showing signs of both a period and a pregnancy. Am I pregnant or am I about to start my period? Please help...
