Any help is so appreciated

This is probably the wrong place to place this, but I’ve received no responses from any other groups. Has anyone had light spotting after missing their period entirely? no pms symptoms and it hasn’t shown up on my liner, but i went to check my cm and noticed a pinkish/Brown tinge to it. Any insights? Here’s my timeline:

Glow, Ovia, Flow and Life all predicted my period on: the 19th-23rd it is now the 24th here in Oki Japan, and still nothing.

However, today i went to check my cm and cp and noticed that my cm was tinged light brown. Has anyone ever experienced and still found out they were pregnant? Is it even possible to have IB 6 days late?

I’ve tested on the first day of my missed period, then again on the 4th day. Both were negative. Still waiting on blood test results.
