i have used NR and it is very convenient and easy to use. i had no side effects. in fact my yeast infection which was not going away for like last 2 years, went away the month i started using NuvaRing. i stopped using NuvaRing as i was not gonna have sex and i got my Yeast infection back. i started using is this month again and i have no yeast anymore. it feels so good to be free from yeast which was so frustrating
