You can't keep one ring in for 3 months, but as the first commenter said, you can stack the rings so that you don't have your period for awhile. I do this because I get bad cramps and breakouts on the off week when I'm on the ring. I keep it in for 4 weeks (if you check the directions, it says if you leave the ring in for 4 weeks you are completely protected) then put a new one in without a ring free week. I can generally do that for a few months until I start spotting a little, then I take an off week to have my period.
