NuvaRing and allergist

I began NuvaRing about 6 months ago. I use one every three weeks, followed by another and only have a period once every nine weeks. When I first started it, I had trouble with terrible cystic acne that took FOREVER to go away. Along the 2-3 week on the ring, I became incredbily tired. I was very edgy, irritable, moody. My sex drive plummeted. I am naseous - no vomiting, though. I have terrible allergies anyway, but I also got a bad rash on my arms. I have polycystic Ovarian syndrome, and I need the BC to couteract the PCOS. Well, NuvaRIng has been the best I have tried. I have tried Yasmin, OrthoEvra, Seasonale, among others. Not to mention no pills, this one gave me the LEAST amount of mood swings....BUT, my allergist gave me a Kenalog shot to help with rash, which immediately went away (and I think helped the cystic acne), and I take Prozac to counteract the mood swings. I am not depressed and have no desire to even think about suicide, but prozac calms me. I am pleasant and even quite humorous. And the sex drive is slowly returning. The nausea is also subsiding. I decided to choose my battles. The side effects of PCOS are much worse than anything I experienced with NuvaRIng.
