Every time after sex, I usually go to urinate, which is normal, but since I've been on NuvaRing for about 3 months now, every time after sex I pee and it stings! I hate this, I first thought I may have a UTI, but after reading what others have said, I now can confirm it's one of the side effects of the NuvaRing. Besides the stinging affect, I love the NuvaRing, it is so convenient not having to take something everyday or every week. I think I will talk to my obgyn and comment on the stinging part.
