1 day late

Canvise
I'm a day late and scared to test. I'm normally late but that's when my Af is set to 28 days. I put my cycle to 32 days and I'm still late. I've been 7 days late with a BFN. Even my husband doesn't want to get his hopes up when I'm late. How many days should I wait before testing? I'm so nervous, can a ovulation kit detect the hormone?
