Any other ladies have trouble keeping their nuva ring in place?

I've been using the nuva ring for almost a year now and I'm never able to get it to stay up around my cervix the whole time. It usually always ends up coming down almost to the opening and I have to push it back up. Any one else had this problem and able to fix it or find a solution? I can live with it, it just gets annoying when I'm doing something and I can physically feel it. Thanks in advanced :)
