For the last couple of days I have had lightly brown tinted jelly like discharge ( the first day it was really brown and thick it looked a little like diarrhea but it was just thick brown discharge ) ... I haven't started my period and but I have the symptoms like tender/sore breasts and cramps every now and then that only last about 30 seconds and come every few hours and don't hurt too much for the last week. Usually by now I would have started bleeding.... But I've only had the discharge.... Could I be pregnant? Or what could be wrong?
