I am 16 years old and currently using NuvaRing to get rid of large ovarian cysts that cause(d) severe pain and would result in infertility when I was older if untreated. I was really worried after reading these comments of the negative side effects - but now I realize it depends on the person, really. Since I have been on it, the pain from the cysts have gone down, although the cysts are still there. I am not entirely sure if NR will entirely eliminate them, but they do kill some of the pain away from doing physical activities and urinating. I have always been around 105 pounds with size C breasts (yes, a wonderful combination that most would kill for!) and being on NR has only increased my weight by one pound, which I can safely say went straight to my breasts. They went from a size C to a D! My breasts are tender sometimes, which is mainly the only negative side effect. However, my mood has, if anything, been more positive since starting NR. I realize most of these comments are probably from women in their 20s or 30s, so maybe age has something to do from it. But as a teenager, it has only helped me. Better yet, I know that when I am ready for sex I will be double protected against pregnancy from condom use and NR.
Anyone who reads these comments and fears NR, do not make up your mind just yet. NR has different side effects for different people, which could be positive or negative. To stereotype NR as a "bad" form of birth control is incorrect. It may not work for one person, but the next person could absolutely love it. Give it a chance, and sure, if the outcome is not what you desired, then I would recommend going off of NR. When you are tampering with your body (in this case, hormonal levels) there are always risks. As long as you know your body's limits and what is okay and not okay, then at least try NuvaRing. It's simple, too - you do not have to remember a pill every day, just a simple ring every three weeks.
I hope I helped someone out!
