... since november 2013. This month's period should've been due already and is the first this late in my life. Whatre my chances of getting pregnant from having sex no condom 4 days ago? The ring will be in 4 weeks tomorrow because I'm hopefully over worrying. My Dr originally told me to keep ring in for 3 weeks and 3 days when I first started and usually my period starts then. I'm worried ... been on NR almost a year
