Late?

Torrie
Well, this is my first cycle, while using Glow. According to Glow, after today I will be 3 days late. Father's day is coming up on Sunday. If "Flo" doesn't show, You think I'll get a positive reading? Or will it be too soon to test? Would be an awesome Father's Day gift to my husband. Also, the 25th marks a year since I've had a miscarriage. And his birthday is on the 27th. Last year was so sad...Is this our come back year!?
