Ethinyl estradiol / norelgestromin
"I've been on the birth control patch for about seven months, and while I've never had issues with forgetting to change it, or it falling off (on the contrary it HURTS when I have to rip them off after a week) I have noticed in the last couple months that on my patch change day I become very light headed and nauseous and usually end up throwing up multiple times over the course of 4-8 hours. I generally feel nauseous, or just unwell for the next three days after as well. I always stuck it to my lower sides, switching each week, but this past week I affixed it to my arm and did find that I was less ill, but I did still throw up multiple times. For this reason I am switching methods because it is not worth it to me to be this sick this often."
