DPO Questions HELP

Tina
I tried conceiving for 13 months and decided to give it up so I stopped stressing taking test every month and just decided if it was in the plan it would happen. So now I'm only 3 days pass my period and it's normally like clock work. If Glow says it's coming it's here but it's not and I'm afraid to test. Should I test or wait a few day?
