AF is late!

Yaz • 28y | Baby boy born 12 June ‘19! 🧔🏻👩🏻🐱👼🏻👶🏻
AF is due any day from the 22nd Nov but still hasn't shown up, and I'm excited to take a PT  because we BDd all through my fertile window this month! TWW ends on the 28th. 
But then again I'm scared to be excited since a missed period is not unusual for me (PCOS) and I've gotten my hopes up before only to be dashed again by BFNs. 
I've promised myself I won't test until the 1st of Dec. I need some positive thoughts please!
