"i have been on yaz for years but changed over to taytulla 2 months ago after moving to the usa and needing a bit more progesterone than the yaz offered. i definitely found myself eating a bit more in the first few weeks and i put on a couple of pounds but i&#039;ve got that back under control now 8 weeks later. i also find that the week of ovulation i am a bit more short tempered with my kids, nothing too serious. yes the first 6 weeks my mood was somewhat different but that can be expected as you are changing the hormone levels in your body. give it 2 months and if you are still unhappy then stop. i&#039;m about to order my first prescription after using the 2 free sample packs."
