NuvaRing and explosion

I've been on NR for almost 2 years. I was fine, I thought, at first. But for the last 3 months I have such severe lower back pain, I can hardly move (and it worsens after sitting for long periods of time)...and it magically lessens after I take out the NR.

Also, I have gained weight that I can't manage to shed, no matter how much I starve myself or workout. I'm heavier than I've ever been at 188 lbs, and my OBGYN when I told her how upset I was about the weight gain told me it was as easy as cutting 100 calories per day - you know one spoon of mayo or piece of cheese...like I'm sitting around spooning mayo out of a jar!

My mood swings are scary - and getting worse every month. I get mad over absolutely nothing and cry and shake with rage...to the point where I've felt like I was going insane, right now I have one "major explosion" per week. I don't want to know what my blood pressure it, I'm sure it's higher than normal, if from nothing else my mood swings. In fact reading your posts out loud to my boyfriend, I've managed to bit his head off and start crying.

I have read & re-read the side effects of NR, with no explanations of this...until I read everyone's posts here.
