I am 20 years old. I just started on birth control about 5 weeks ago. After the second week of starting I started to get brown spotting very light. Then it got heavier but really dark, not like my periods (which have been regular for as long as I can remember) and this was two weeks before I was supposed to get my period. That lasted about 7 days, normally my periods last 4-5 days. Then the brown spotting/discharge remained for about three and a half weeks. It is only for a little bit everyday but I really don't like it. Now I am getting pain and it is starting to freak me out. :eek: I have been having sex with my boyfriend for about four months now. I took a pregnancy test which was negative. WHAT IS GOING ON AND WHAT SHOULD I DO!
