Help me pls

I'm in my 1st month of trying for my 2nd baby. Usually my period starts on CD32 - it's always on time and the day before I get bright red spotting that fills a panty liner leading into a period. I never get spotting beforehand.

So at 12dpo (5 days before my period I get light pink spotting like this):

It doesn't get any darker than that photo but remains like this throughout 13dpo:

And then stops completely on 14dpo. I havent got a positive test at all (periods due tomorrow) and now i have this at 15dpo usually my discharge is dry before a period:

Has anyone not got a bfp or faint line until after their period or am I completely out?
