Do you start when you’re supposed to?

Chandler • Maybe just happy🌻

I was jut wondering if people actually know when they are going to start?

Mine comes a week or two early always, and can last 14 days and then some spotting. But this month I haven’t had anything, my chart says I should start tomorrow. (Don’t know how accurate that can be considering my period is so weird)

Just wondering if y’all actually start the day you’re supposed to?
