I really liked the nuvaring, I was on it for a year after having my fifth child, when I switched to an iud. I had NO problems whatsoever, I just wanted something I could 'forget about' without anything permanent being done. I HATED the shot the two times I was on it. Both times, when I quit and tried to get pregnant again, it took me over a year to get pregnant, almost two years of trying. Both times, I lost the first pregnancy early. And I gained weight.
The nuvaring reminded me of a jelly bracelet, you'd fold it in half and insert it. You didn't have to go extremely far up to let go, either, it fit itself into place. Nothing 'out of the ordinary' for me with it. Go to the website and check it out.
Sorry, the kids spaced me out, I also forgot to mention... Nuvaring did not damage my milk supply, nor judging by my sons pudgy cheeks, quality. I got light periods. Do NOT go on mirena iud if you want to have kids in less than five years unless your dr says so.
