5 days late! But is this normal....?

Faye • TTC after an ectopic pregnancy in 2013. Still no luck :(
So as you can see my AF is 5 days late. But for 2 days I am having very light brown spotting. It's not unusual for me to be late due to my PCOS. But I have had little to no cramps, no AF symptoms apart from the spotting. Usually after a few hours of spotting AF arrives heavy and red. But not this time...anyone else had this sort of spotting and still managed to get a BFP??? Going to purchase a HPT on Tuesday if AF still hasn't arrived 😬 thank you in advance ! 😘
