Hi, It's called a Nuva Ring and it's not actually an IUD. I just started with one this week. No more remembering (or in my case forgetting) to take the pill every day!!!! It's a soft clear ring, about the size, thickness and flexibility of a hair elastic. You insert it into the vagina and it stays in for three weeks. After three weeks you take it out and toss it. You 'll then get your period. One week after you took it out you put a new one in. It works by releasing the hormones found in the birth control pill over the three weeks you have it in. My GYN is recommending it to alot of his patients because the efficiency is 98% and because it releases less hormones into your body that the standard pill. I've had it in since Wednesday and I definitely can't feel it. However, it's getting the first real tryout tonight..if you know what I mean...I'll keep you posted.
