Help?!?

I’m on the nuvaring & last Friday I got my period so I was on my ring free week & that week I’m still protected, my bf and I decided to have sex on Sunday, when we finished we noticed the condom was deep inside of me and we had to pull it out, on Monday was my day to put in my new nuvaring and I put it in on time but I was still on my period when I put the ring in, am I still protected? I know every time I put a new ring, I always get the same symptoms which is a tired/draining feeling and I did feel that, should I not worry? I’m just curious
