Nuva ring question about pregnancy

Hey guys so I recently took out my Nuva ring cuz me and my husband want to start trying and I saw that according to the app I was going to be ovulating soon, now I don't really know if you can ovulate when on Nuva ring or anything but I got a lot of cramping and 4-5 days after I took the ring out I got my period for like 3 days. We had sex 3 days of my most important ovulation days. My question is does anyone have any experience with getting pregnant after the Nuva ring and if there was any way that I did still ovulate even with having the period or should I retry during my next ovulation time?
