I am happy to say I have never and will never take NuvaRing, I myself am on Ortho-Tri and have been for 7yrs. But one of my dear friends is in the hospital fighting for her life due to this ring. She is now in her third surgery in the past few days because of numerous blood clots threw out her body due to starting NuvaRing 8 months ago. My suggestion if you are taking this and all drugs to keep a close eye on them. Her situation is become very serious. And she never had a single problem before now. And two beautiful children later she is left with a bad side effect. This is way a drug should not be EXPERIMENTAL on humans. Ladies please be couscous of your life and the FDA approved drugs!
