Ocella
"I've been on Ocella for about 8 months now, and its been decent but I am looking for a new birth control. I'm 26 years old, and have used several different pills before including Alesse and  Lo-ovral. I found out I am allergic to synthetic progesterone (norgestrel and alike ) in virtually every birth control available, which is why I switched to Ocella. Ocella has done the job as far as preventing pregnancy, but I have had mood swings bad enough to start taking Welbutrin, I've gained some weight, and MY SEX DRIVE IS TERRIBLE. The mood changes and the HUGE sex drive decline is the reason why I will be changing again. I'm also worried about all of the warnings on Yaz/Ocella/ Yasmin and the high incidence of strokes associated."
