Ugh!! I am 33 and have recently been having toruble with BC pills, the usual extreme mood swings and such. Went off of all BC pills to help get my body back on track. I am newly married and we are not ready for kids yet, so thought I would try a new BC. Just started the Nuva Ring on Friday (so it has been 4 days on the ring) and I feel terrible. I feel like I am sick with abdominal pain, night sweats, numbness in my arms, headaches and the worst is the nausea. I just want to take it out, but not sure if it is something that will go away. Any words of wisdom? From this site though it seems as if I should just take it out and hope I feel better. Just want to crawl into bed and stay there.
