The nuvaring should be re- named to the devil ring. I went on it for two days about a year ago. I went for a jog (like i have been doing every day for years) and felt this horrible cramp in my pelvic area. I had to sit on the curb and almost flagged somebody down to take me to the ER because I could not get up. Finally, I made it home, took out the ring, and about a half hour later I was fine. People thought I was crazy when I attributed it to the ring so I decided to go on it again last week. I immediately felt very much not like myself. I was on vacation with my family and was so extremely moody and irritable I was just un-bearable to be around. I had it in for 7 days before I decided to remove the ring. Once removed, about a half hour later I was much more pleasant and less irritable. It has been 6 days since I removed the ring and I have gotten my period. I experienced terrible terrible cramps yesterday to the point that while shopping I was huddled over in the aisle because I kept getting this shooting pain from my back to my lower abdomen. I have also been having very bad night sweats (I wake up in the middle of the night and have to shower because my clothes are completely drenched). Now, today I have a very bad migraine, I am experiencing the chills and sweats with no fever. I have made an appt w my GYN for Monday but its Friday...that means I have to go through two more days of this. Has anyone experienced similar symptoms even when the ring has been removed?
