"i&#039;ve been on the nuvaring for several years, and because it&#039;s so expensive i&#039;m switching to an iud. side effects have been very mild, such as slight decrease in vaginal lubrication, occasional vaginal irritation, and slight decrease in sex drive. it was overall a positive experience, but it costs so much and i&#039;m hoping the lower hormone doses in an iud will boost my sex drive a bit."
