After losing weight, I went from having no period for 2 years, to spotting every 2 weeks once I started college. My gyno put me on this to regulate it again. I had a headache the first 3 days but I think my body was just getting used to it. I don't really think I gained weight either. However, today almost marks my second week on it and I'm bleeding the heaviest I've ever bled before along with backaches and a little cramping, fatigue, etc. Granted, I was using monistat 3 this week to treat a yeast infection but I'm not sure if that has anything to do with me getting my period. Has this happened to anyone else? Should I stay on the pill and see what happens?
