No they are not the same.
Yasmin or Ocella is
a lower dose of birth conrtol, while
Yaz is prescribed more often to those who suffer from PMDD (Premenstrual dysphoric disorder). Yasmin is one of the best birth control pills out there for those who suffer with PCOS. I've been on it for 2 years, with a break of 6 months. I just started a new pill pack this month again. I too suffer from migraines, but the pill does not give me any.
