birth control
"I've been on Nuvaring for almost a month. The first week I started on my period and it lasted only 4 days compared to 7 days. I felt sick for about a week plus breast tenderness. But I've had no weight gain, no nothing after the first week! I love it. And if your wondering if you can feel it ... Well you can't if you put it high in your vagina it did slip down during my first week but other than that good! My partner wasn't able to feel the ring either. Nuvaring works for me."
