"i only used nuvaring for 8 days. i didn&#039;t have cramping or anything but in the first 5 days i gained 5 lbs despite exercising 5 days per week.  i also started salivating a lot more (on the verge of drooling), had a much increased appetite, was nauseous, and on the day i decided to remove it, i was very dizzy for most of the day, nauseous, and had a headache. i think i&#039;ll be going with a copper iud."
