Online I misread how long it should be kept in. (I have been keeping it in 28 days, for 3 months now) ... now I know it's 21 days. The nuva ring website is kind of unclear about leaving the ring in too long! If I left it in 28 days, take it out the 28th day and put a new one in a week later am I still protected? I had unprotected sex 2 days after I took it out, and on day 3 got my period like I usually do. Should I look into taking plan b?
