Well, I have fibroid tumors and I also just lost an ovary because it had a large dermoid tumor. My doctor suggested the ring for me because it could help balance the hormones from the fibroid and keep me from ovulating which could contribute to me developing cysts or another dermoid on my one remaining ovary. I have been on the ring and I loved it at first. Before the ring my period was coming every 14 days with horrible symptoms. With the ring my period was coming once a month, with very little cramping. Then other side effects have started, first my hair started thinning, every time I washed my hair I would pull out a bunch. Then I gained almost 8 pounds. Now I have terrible insomnia, moodiness and depression. I seriously have not understood what was wrong with me until I came to this website. I will call my doctor tomorrow.
