Nuvaring

I was on the Nuvaring for a year. Me and my husband want to have a baby so I took it out May 17th for my upcoming period. I got my period on the 20th. I didn't put the Nuvaring back in. My chart said I'm ovulating the 3rd of June. We basically had sex that whole week. I guess I ovulated, because I experienced that clear egg white mocus for about one day on the 1st of June. Maybe a week after I had soreness on my nipples, I was nausea and just eating a little more than I do. I don't know what it might be, maybe it's from the withdrawal of the birth control. But now my period is a day late. I have mild cramping, went to the bathroom and my period didn't come. So should I wait a few more days to take a pregnancy test?
