Hi, I just wanted to share with you that although I have never tried YAZ (but have considered it) I am currently on the Nuvaring, and I absolutely love it. The side-effects from the hormones are minimal if any, periods are regular, and I am not gaining any weight. My baby is 8-months old and I've been on the ring from the time I stopped nursing at around 8 weeks on. So, just an FYI in case you decide to seek another method, the ring is great! =)
