I began NuvaRing about 2 weeks and today I had to take it bc I could not stand another day- I was on it about a year ago and my body seemed to tolerate it better then with fewer side effects. 2 days after being on it i experienced sudden sharp pain in my upper back- i couldn't even carry my power book. For the rest of the week I experienced extreme fatigue and serious depression. I am generally a very positive person and I haven't experienced something as intense as this. By the end of the weekend I was having period like feelings in my pelvic area and EXTREME breast/nipple soreness. My breasts seem to be firmer and a little larger, but the pain was so intense. My appetite seems to have decrease, but I am bloated and still so sluggish. I felt slightly anxious as well. The worst part was the lower back pain. It was so uncomfortable that I couldn't sleep well and haven't for about 5 days. I took the ring out this am and within an hour the back pain had subsided. I am not sure how this will effect my period- that is- if it will come early- or if it will disrupt my cycle. Any experience with this anyone?
