Confused

Theresa
So AF was due yesterday, I took a test today and got a BFN. I am never late. The last time I was late I found out we were expecting our first child. So we are now on day 2 with AF as a no show. I work nights so FMU isn't a thing for me. I will test tomorrow afternoon when I get up. I just don't understand. Any tips or advise to give?
