My dr told me it only affects the reproductive organs so there are no other side effects, but I'm inclined to believe she's wrong, because if there are artificial hormones in your body there are artificial hormones in your body, whether you take them by mouth or vagina.

However - I looked at the prescribing information for the Nuvaring and compared the ingredients to Ortho-Tricyclen, and there are less hormones in the Nuvaring (roughly a third to a half of what's in Ortho-Tri. So there would probably be less side effects if any.

Also, the prescribing information for Nuvaring does mention all of the side effects of most birth control pills. If my dr is right, this is probably just the pharmaceutical company being sure to cover its ass in case of any adverse effects.
