I've been bleeding this brown stuff for almost 2 weeks! It first started out as pink spotting for 2 days then the rest of the week went on just spotting brown stuff.. I don't know what to do! I've started some symptoms of pregnancy... I went to the doctor and she said its to early to tell. But my thyroid tests came back too low could this be it? And I'm 20, some one please help! I'm scared!
