I had the same trouble with the Pill - my stomach DID NOT like the idea of hormones through the stomach lining... but NuvaRing, since it's soaked up constantly thru your vaginal walls, it doesn't really go near your stomach. I never had any side effects at all, and it has only slipped out once (last week actually) on the whole three years I've been on it. I also noticed I got fewer pimples, but I don't think I gained any weight (I was actually rooting for that side effect because I'm so thin). But I'm this huge NuvaRing supporter, I just love it so much
