Anyone experience this???

So I’m now on CD 39 which makes me 4 days late. I had what looked like a vvvvfl on 8dpo and hen a string of vvvfl/indents on FRER, clearblue, cvs brand and on the day of AF (CD 35) I had some faint pink colored discharge when I checked my cervical position and cm. Picture below

So I assumed AF was coming and that was my answer, and I had blood taken that morning which showed less than 1 hcg in my system. But after I got the picture above I had no more colored discharge. All clear or white. My cervix stays high and closed. I tried having sex to see if maybe that would bring the bleeding back and nothing happened. No blood from sex. I took this test yesterday and it was a vvvvvvfl

Today I take a FRER and saw the same indent so I tried with the last cvs brand I had left and got this

I am seriously confused. I’ve spent well over 100$ on tests since I started testing at 8dpo
