Nuva Ring

Question for those who have used nuva ring. The last day of my period the week of Thanksgiving I put my ring in like scheduled. The next day my dh told me he was ready to start trying again so I took it out. About 5 days later I had what seemed like another period that only lasted a few days. Since then I haven't had a period. Has anyone else had this happen? We are ttc our third but without having a period I can't follow an ovulation calender. We've had regular sex but is it really possible to get preg that soon after stopping the ring?
