i am 15 and was due for my period. instead of my period i got some nasty thick brown mucus like dishcharge i guess you could say. it wasn't painful or smelly just odd. i am sexually active but i have been on the ortho evra ptch for a while now. it seemed to have gone away or started to and i started to get blood with it but it just went away. and the brownstuff just kind of came and left as it pleased during the time of my normal cycle, then it stopped. whats wrong?
