Pregnancy

I take the nuvaring and this cycle tried a new thing. Instead of leaving it in for three I left it in for almost six accidentally. And instead of Leaving it out I put one right back in I heard you don't get your period thst way. And I haven't yet and I forgot when my last period was and I'm a little worried and am too nervous to buy a test. I was think I'd use the ring regularly this cycle and see what happens but advice would be nice.
