Hi everyone I am 20 years old. I never had a period I only had the brown stuff.. When I turn 17 they did a lot of blood work to see if my hormones and everything was okay. The test came out great no problems or anything they did an ultra sound to make sure everything was normal and yes it was they wanted to do the vaginal ultra sound but that time I was a virgin they didn't want to put anything.. When I was 19 I lost my virginity so I went to the doctors did blood work again everything was normal now they wanted the vaginal ultra sound they did it everything was normal I ask my doctor if I could get pregnant later on and she said yes that the brown stuff is also my period. I been on birth control for 2 years now.... I want to know what everyone thinks
