This happens every single time I put the new patch on. Lasts through out the day it is terrible. I am naturally underweight and wasn't menstruating regularly so I went on birth control. Luckily, I gained weight too (a plus! only five or eight pounds) but the nausea and vomiting is so terrible. I have tried to go off of birth control, but I dropped weight and stopped getting my period... I feel very stuck and very sick and I need help!
