Hello, I've recently started taking Yasmin as birth control (I am on my first pack and 3rd week). I've taken Diane 35 in the past before, but I've taken a break between the two pills. I've been experiencing bleeding and thick black discharge but I am not on my period. Is this normal? It looks worrying to me. I am also currently taking roaccutane 20mg a day. Should I continue taking Yasmin or stop mid cycle?
