I've been on the nuvaring since march and it has work pretty good for me. It has cleared up my acne, i just have a few bumps here and there when my cycle is on.it also has my cycle a lot shorter. I have been having pains in my hip and knees to the point where i don't want to do anything but lay in bed all day, it use to been all the time but now it pain only when my cycle comes on and a week or two after it ends. Recently I just started to get real bad migraines,tiredness, nausea and numbness in my legs from time to time. sometimes my legs give out on me. Also i started to itch and i been scratching to the point where i have cuts and its burns when use the bathroom.
