I have been on a generic of Seasonale for 3 years now, and I've recently experienced something strange. I began to experience symptoms of pms (and I have pmdd which this birth control is meant to help control) over a month before I am supposed to get my period. I've never experienced pms so early, and the intense mood swings have made my life very difficult. For the past two weeks I've basically been clinically depressed because of this, but I've suddenly snapped out of it. I made an appointment with my doctor for next week, but I was wondering if anyone else had experienced this. This is the first time I've had such dramatic symptoms so early.
