Advice, please

According to Glow, I was suppose to get AF on Sunday. This means I am three days late. I’ve taken two pregnancy test and both were negative. I’m the type that gets her period every single month, on the day I’m suppose to (28 day cycle). I don’t know what to think. I’m praying that I’m pregnant, because the thought of missing my period for any other reason scares the hell out of me.
