Just started with Nuvaring a week ago. Haven't been on any birth control in over 5 years. I don't know if these are common to all hormonal birth control methods but have been experiencing nausea, dizziness, anxiety, mood swings, pelvic soreness, and I can feel the ring; in general and during intercourse. My boyfriend can feel it, too. Also, there is some vaginal discharge that smells funny. Not strong, just funny. The mood swings are intense, from crying for almost no reason, to a strong sense of anxiety. My sleep has been disturbed due to a general sense of nervousness. I think after this month, I will switch to the pill.
