Hello. I was prescribed Larissia birth control pills for my long painful heavy menstrual cycles. My menstrual cycles usually last 7-8 days. I started taking Larissia on my first day of my menstrual cycle. The first two days was heavy, the third through the sixth day the flow kept getting lighter, then seventh day I started getting bad cramps, feeling nauseous, and my flow got heavy. Today is the eighth day, I took Larissia in the morning and instantly start feeling nauseous, bad cramps,having diarrhea, and heavy flow. I would like some advice on what should I do to ease the side effects?
