10dpo. AF due today.

I'm 10 dpo and glow says AF is due today. So far only super like spotting. Like only 5 drops on a panty liner. Taken some test but looked negative. Although one tweaker said she saw a faint second line. Should I wait a few more days to test if AF doesn't come today? I know most of you guys go more days passed ovulation than 10 before your periods. I'm really hoping AF doesn't come.
