I have been on BC pills (Desogen) for years. A few mos ago I started taking Ovcon 35 to try to shrink an ovarian cyst. It did not work so I started Ovcon 50 about a week ago. Since then I have been experiencing bad side effects such as severe mood swings (almost like being manic/depressive) sleeplessness, nausea, dizziness, and headache. Is this normal, because I think I am going to stop taking these and go back to Ovcon 35 (which was great).
