NuvaRing and ear infection

I can not say that NuvaRing is the reason for my illnesses but I am a fitness competitor and athlete and have always been very healthy with the exception of IBS that was diagnosed 5 or 6 years ago.
I am 37 years old and started using NR in August of 2008. In late August I went to emergency for extreme pain in my back and stomach. They put me in surgery to remove what turned out to be healthy appendix. Since then I have been to the Dr constantly with fevers, sinus infections, ear infection, bronchitis and most recently am undergoing tests to find out why my kidneys and pancreas are infected. I have been on antibiotics 4 times since January.
I started putting time lines together and decided to research the NR further. After looking at many symptoms, I opted to take the NR out in April of this year and go back to the pill.
I go back for another set of tests on my kidneys and pancreas next week and hope to find all is well. I have been off antibiotics now for 3 weeks and no sinus, ear or upper respiratory infections for the first time in month.
This is all unfortunate because I did appreciate the convenience of the NR but I am not willing to risk my health.

I started using the nuvaring 2 months ago, and just recently got a yeast infection. I'm not sure if it's from the nuvaring though, because I was on Augmentin for an ear infection as well. Anyways, I have gained about 5 pounds while on it and have had quite a few mood swings. I've also noticed that I have been a little depressed lately. I'm supposed to take it out on Thursday and I think I will just quit altogether.
