birth control
"Used the ring for 6 months.  I gained 20 pounds. I went from 120 to 140. Its not very easy for me to gain weight. Had a lot of discharge that made it extremely uncomfortable. I never get yeast infections and got one on the ring. And my sex drive went way down on the ring. I am switching back to the pill cause I've never had any problems with the pill only minor and I've used the pill for 3  years."
