I have been on the Nuva Ring since Sept. 2005 and I have highly recommended it. I switched from the pill because of adverse side effects that I was having even, on the so called Lo dose ones. I not longer suffer from any side effects. And I love that you don't have to worry about for three weeks until it is time to remove it. If you go to their website I found that the Nuva Time Program for the computer really helps you know exactly when to insert & remove. Also they will send you a small timer reminder for your purse if you sign up to the club. I hope that it works out for you as well as it does for me.
I just started the NuvaRing myself about a month ago. I did notice a bit of moodiness in the begining, but I am going to be starting my second month on Wednesday and so far, I love it. I had some diffuculty remembering to take the pill on time and this is just great!! I also have my first period while on it and it's not bad at all. It's not as heavy and painful as they used to be. I don't really notice it during sex, but I have been taking it out because of other issues that I have, but if it weren't for that, I wouldn't even bother. My boyfriend never feels it at all. I did notive a few headaches also in the begining, but since the first week, nothing. So regardless all the bad comments I have read about the NuvaRing before I started it, I love it.
Good Luck!
