how soon is nuvaring effective
Nuva ring effective in 7 days? How does this work? I just started Nuva ring, actually it's my first birth control, and my doctor said that it only takes 7 days to become effective. I've always heard it takes a FULL Cycle...It's making me think about how many hormones are actually in the ring... does anyone know why it only takes 7 days opposed to a full cyle? thanks.
