I'm becoming very concerned with my discharges because its been non stop the past three maybe four weeks..most of the time its mucus brown..other times its almost black..but then other times when i use the restroom i bleed red..its not alot but some to see..I have been sexually active and I'm concerned if I may be pregnant because I havnt gotten my normal period..I bleed red so I can't say if I am or not..I'm having to use liners because the brown stuff makes it seem like I'm on my period..I don't know..can someone help me??
