I am here to let women know that nuvaring will cause a decrease and or lost of appetite. I put my first ring in 1/11/15 & today is 1/20/15. It's only been 9 days! & I cannot eat. I've lost about 2-3lbs. So be aware first time users of the nuvaring. It doesn't happen to all women Because as u know most women gain weight on birth control.
