5 days late

Sunny

What does this mean?? Here are the lengths of my past cycles, Oct 30 days, Nov 29, Dec 29, Jan 29. Per the app algorithm I was supposed to start the 7th (29 days). Nothing. On the 10th I took a test and it was negative. Today I'm 5 days late (unless I jinxed myself and I start today). How long after a missed period do I wait??
