To tell or not to tell your spouse

Erica
When your AF is late, how many days go by until your tell your spouse? Do you update him daily, wait a week to see if your period came, test & then tell him? This is my 2nd month in a row with AF coming late but last month I felt that I took him on the emotional roller coaster with me only for 6 days to pass and she showed up so not sure if I want to take him through that again or wait till it's been longer. All thoughts ideas are appreciated.
