Glow Tasks

Jade
This is my first time posting! AF is due Wednesday but today my glow tasks are telling me to do a pregnancy test - is that normal? 
I was going to try and, impatiently, wait to see if AF was late before doing a test but it's very tempting to do one now! 
I'm nervous because my husband & I have been ttc for over 2 1/2 year& have had two miscarriages. I hate doing tests as its such a disappointment getting a bfn... 😔 
Does everyone get a task to do a pregnancy test a few days before AF? xx
