I've been on the Nuva Ring for a year and at first i didnt' get any side effects but maybe 3-4 months ago ive had terrible mood swings, i feel very depressed, mayor loss of hair, i also got a tingling on my right arm and currently experience leg pain..often get headaches, weight gain, breast enlargement, spotty darkening of my skin (face). I'm getting off the Nuva Ring this month. I don't recommend it!
