Should I wait?

Today is supposed to be my last day of my period but I haven't started. I've been ttc for 6 months and this is the first month I've used Glow. I took an early test and then I took one on the first day it said I should test. They were both negative. On the first day I was supposed to start I spotted once. I thought I was about to start and I never did. When should I test again? BTW I don't feel any different. Kinda lazy today but I think thats more because my mind is all about whether I'm pregnant or not
