I've been on NuvaRing for a year and I thought It was working great. After having two rings "disappear" I decided to talk to my doctor about a different form of b/c. I have not had a ring in this month and I cannot believe the sex drive I have now. I'm single so I hadn't really noticed it was gone but now that it's back I realize how much the NR had affected me. As I was reading posts here I was amazed at how many symptoms I share with others. I have always been prone to headaches but since starting this a year ago they got more frequent and more intense. I also had issues with fatigue, however, being a single parent of a one year old I just kept blaming the baby but so far this month without the ring I hardly ever need a nap anymore. I have also noticed my mood swings are not as severe...I won't blame NR for all my moodiness because I have always been a moody person but I can tell a difference. I never had problems with the nausea or charleyhorses or tender breasts but all hormones have a different effect on different people. NR may work well for some and to those I wish congrats. I am hoping that my new method of b/c works out for me but I will be paying attention this time to what the hormones are doing to my body.
