Which chart should I go by?

J • Living the blessed life with my husband and 2 year old! Baby number 2 is on the way!🔆👶🏻 #allboymomma

Both cycle lengths are put in as 28 in both apps. Premom is telling me I’m 10 days late and glow is telling me 2 days late (3 days today). Which chart should I go by? Because I want to go to my obgyn but I don’t know if I’m actually 3 days late or 10 days.
