AF due today, orange spotting?

Jess
Glow and Ovia predicted my period should show today or yesterday. 
​Yesterday I got a faint BFP when AF didn't show, and today I'm having watery CM with an orange tinge. 
​It isn't noticeable on toilet paper, only with a finger check. And I have super light cramps. 
​What do you ladies think? So hoping for a little bean, would have been conceived on my birthday!
