I had Nuva Ring. Me and my friend got it together but for her was perfect, but for me it was pathetic!!! dizzy, cramp, headache, nausea, back pain, and extra extra heavy period, it was incredible how i took it out and 1 hr later i was completely normal, all the listed syntoms dissapear. Ever again!!! My friend is bn using it for over 5 months and everything is perfect. Hope this help ;)
