Looking for advice! 4 days late & -HPTs!

Okay soooo.. I'm not sure where to fully start. Ill try to make this short and sweet... But... Here is my calender first for the current cycle.

On Jan 14th I got a opk with strong line which I took as a positive. It was the wondfo brand.. Then on Jan. 22 - 25 I had VERY VERY light brown tan colored discharge.... Only when wiping.. It looked like this:(im showing a few pics)

Then the day before expected AF Jan.29th I got this:

So the fact this discharge had the red speck made me assume maybe I ovulated later then I thought? I have NEVER had discharge with a red speck like this.. I'm currently 4 days late for AF. I have a very regular 34 day cycle. So to be late is strange for me... I am wondering what the red speck can be from..and I'm getting BFNs.. Any ideas? Praying i have some good hope still. I only am having very light faint cramps on my lower left back above my butt and my nipples are puffy looking here and there.
