Last month after I stopped using the Nuva Ring, I had the most incredible pregnancy symptoms. (nipples swelled and sensitive, extreems tiredness, peeing constantly, and one spot of pink blood which I could only explain as implantation bleeding). My body has never had such symptoms, even after comming down from the pill and the patch. I still am experiencing the nipple systems even after my first perfectly timmed period. This however is not a documented symptom. I only found two other women online who have experienced the same exact symptoms after comming off of nuvaring. They were saying that it may last for months for me.
