Hi C.,
I have used NuvaRing before - When I initially tried it, I really enjoyed not having the usual side-effects of birth control, however, during the 9th month of using it, I got pregnant - before it was taken out. Big shock. But my doctor advised that I must have been that 10th of a percent of that "99.9% effectiveness" claim. So earlier this year after delivery, I decided to try it again after my doctor suggested it. After the 3rd week of using it, one day out of the blue, I started feeling sick-nauseated, flu-like symptoms. By day 3, I was feeling worse -very week and having migraine-like headaches, so I went to the doctor - the dr. said I had a stomach flu, but by the end of the day I started to lose vision. My husband, an Ophthalmologist, said this wasn't a flu. And then I wondered if it could be the Nuva Ring, so I took it out and within 30 min. ALL symptoms were gone. This had never happened when I used it previously. So after all this, I'm not interested in using it again. But of course, I still may be that 10th of a percent. Recently I have tried Loestrin Fe and like it. It is pretty expensive, though.
Hope you can find the right fit for you.
K.
