Hi, I m 19, 5 7 and 10st. My question is I was on yasminelle for a few months and came off it for 3 months , and I ve just finished my first pack after going back on it, I began it on the first day of my period and that period never quite went away, I have been lightly bleeding and having brown discharge for 4 weeks now, I never missed a pill and I take it religiously, I m really worried, please help!
