severe breakthrough bleeding,nonstop bleeding for 2 weeks...

I have had same thing. There is next to nothing in the materials they give with the product that warns of this. They mention possible "breakthrough bleeding" which anyone other than a doctor would think of as possible spotting between periods. But I have had non-stop, heavy bleeding for 9 straight days with no apparent "end" in sight.

I used nuvaring once about 3 years ago and did not have this problem. (In fact, then it viirtually stopped my period.) That concerned me, so I stopped taking it. I went back on after my doctor assured me the reduced bleeding was not a concern, and the main PURPOSE for use was to reduce my heavy periods and related anemia, Apparently they have changed the hormone dose in the nuvaring, and for some of us it is insufficient, producing the bleeding. (It has taken EXTENSIVE web searching to glean this information.)

Personally, I have removed the nuvaring, and while I guess it may take some time, I want my body to normalize from this shock. I've had nausea, and now I am very fatigued from the extended heavy bleeding. This is NOT what I signed up for. I think there need to be improved warnings and disclosures provided by doctors and with the product. Hope this helps. KN
