Is there any progression? I’m confused !

Sorry i know I’m supposed to post this on the faint lines group, I will post it there.. but I just wanna know if this happened to any of you from experience

I posted this before yesterday I was 11 DPO

I had a very faint line

I took another one just now 13 DPO

But it’s still super faint! I thought it will be so obvious and dark but...

Is this normal or shall I go do blood test?
