Ok so I recently started nuva ring, this is my 2nd week, and me and my boyfriend decided to have sex with it for the first time. After having sex I felt a slight burning so i went to the bathroom checked it out and i realised that my left labia was red swollen and extremely tender! I put ice on it but it did nothing for the swelling, although it did take some of the pain away. Does anyone have any idea what could be going on? (i read it could be from roughness but this does not seem likely) Does it have anything t do with the nuvaring? How can i get the swelling to go down? Please help! Thanks!
