I really hope I'm wrong but if you were ovulating around CD24 when you DTD and you are now CD 47 that's 23dpo which would mean if you were pregnant then the tests would be coming up with very obvious strong line by now. Lines roughly show up between 10-15 dpo.
I don't think this is your month but I hope you get things sorted and are pregnant in the near future.
Given your history with PCOS and irregular cycles, it's probably playing silly buggers on you again. Strange for EWCM as that's more an O symptom and it usually is creamy in early pregnancy?
