Should I take a test if my period is 5 days late ? According to Glow I was suppose to start my period on the 21st and it’s now the 25th :O

I really want it to be that I’m pregnant because I’m always on time, and so far this app is accurate on when my period will start. But in June I had a late period but not this late. My cycle is 37 days and no period.

What do you all think?
