"this is very convenient but slightly expensive. my major side effect is no sex drive! i had a very healthy sexual appetite prior to going on nuvaring but now it is nonexistent. i also have crazy pms, very angry, i actually put it on the family calendar so people can beware.  but haven&#039;t had anymore migraines since going on which is why i have to take birth control (regulates my hormones) but i&#039;m seriously considering going off just because of the 2 side effects i am having."
