birth control
"I am not sure how long I have been on Nuvaring but it can't be more than 3-4months. All I know is that since I've been on it I've had massive headaches weeks at a time and nausea constantly and I wanted to trigger that at my gluten sensitivity and maybe eating something wrong. But apparently some people have been experiencing the same symptoms. Other symptoms I've had: 
Constipation, 15lbs weight loss, dryness, crazy hormones, and no desire to eat or have sex. I still have sex regularly but I don't think about it constantly like I used to."
