I started the NuvaRing on Oct 1 and felt a flu coming on Oct 5. Oct 6 I had a horrible headache and fever which has been between 99.3 and 100.5. On the 10th I awoke vomiting and developed a yeast infection. It just dawned on me it might be the ring. I googled and found this page. I'll see my general physician tomorrow, not the OBGYN who sold this on me when I complained about heavy periods. I'm using this not as a birth control but pre-men stabilizer. I'm thinking to yank it right now...?
