Can Duromine Affect Menstrual Cycle? I've Got Pcos And Metformin

Can duromine affect menstrual cycle? I've got pcos and metformin helped me regulate it more or less. Then my doctors stand in put me on duromine. My first period was light and short this time I'm have all the symptoms of pms with no sign of period. For over a week now and all tests come back negative.
