I had an abnormal bleeding problem (my dr thought it was pid) it lasted 3-4 weeks, he put me on birth control to stop the bleeding, which it helped and he wanted me on the birth control for 2 months to regulate me again and to stop bleeding if it started again- it hasnt started bleeding again except for excessive breakthru bleeding as he called it- ramped up the birth control then this month i have yet to have my period- I know that when i am on birth control when i take antibiotics the birth control is not as effective (we dont want to prevent pregnancy anyways) and have had a break out like acne/ hives style on arms,chest, stomach, and legs, I also have nausea , fatigue , breast tenderness and other pregnancy signs- I took a generic version of EPT on Friday 13th,2012 and it came out very faint positive- it faded away a few minutes later and came back after the 10 minute limit- could this be a false positive or could it be to early or a sign i am going to lose this baby (i have history of miscarriages) if i am pregnant .
