It all started when I was 16, when I had my first period. It was "normal" for about a year and a half. After that things went wacked. I stared to miss cycles so my doctor put me on birth control. It became "normal" as long as I was on it. I had to go off it cause I developed an allergic reaction to it. I was 19 when I stopped taking it. I am now 26 and have not had a "normal" period since then. I will spot or bleed for about 24 hours then it stops and I have a brown discharge for a day. After that I won't have a period for about 2-3 days then I spot or bleed again with the brown discharge after. What is wrong?
