8 days late...BFN

Ladies I'm 8 days late...tests come bk negative. I'm 9 months Pp but periods have been regular since birth. I'm never late unless pregnant and any time I've been pregnant I've gotten positives few days before period or day of! Totally out of the ordinary for me.

I assume if I was pregnant I'd be having blazing positives right now or has anyone taken a while to get a positive??

Ovulated on time...had ewcm as normal for me..however 8 days later I had ewcm again for two days...cud this be the issue? So frustrating
