"the nuvaring was perfect for me except for one thing- it caused me to have a yeast infection. i didn&#039;t know that i had an infection (my symptoms were one spot that was really itchy and fishy smelling discharge for about two-four days every month) and i left it untreated for months which caused it to be horrible (well, i don&#039;t know if the nuvaring made it horrible or me leaving it untreated caused that). when i finally went to the gyno i had to go off of it and immediately be put on yeast pills and i had to put a cream on twice a day for three weeks. it also caused me to have an increase in vaginal discharge so i just wore pantyliner everyday. outside of those things, it was great. no acne, weight gain, mood swings, or nausea."
