Missed pill!

I missed my pill and took it the next day, my boyfriend, FULLY AWARE THAT I MISSED IT, and I had sex (unprotected) and he came inside me. I start my period in 6 days. Should I be worried that I might be pregnant or should I not stress it too much? When should I take a pregnancy test?

We are both old enough that if I was pregnant it wouldn’t be that huge of a deal and we could make things work.

Thanks!
