AF Due 17/09 Thursday...

Manda
Glow is telling me to take a test today, but I'm on month 6 of ttc and I hate the disappointment each month. I've ordered some tests online which should arrive tomorrow. Do you think I should test tomorrow or try leave it till Thurs is AF doesn't show? Usually ill get spotting days before AF is due and so far I've not had any this month... no symptoms really just feeling tired & drained.
