Testing Question

Teresa
So I'll start this by saying I have been traveling for two days starting Saturday afternoon and just touched down at home this morning. Onto my question.... My period should have started Friday. And now on Sunday I still haven't seen it. I feel like I'm setting myself up for failure by hoping. I know high levels of stress can make your period janky but mine is clockwork regular. Should I go ahead and test in the morning or wait a few more days?
