So confused???

I took a pregnancy test on Monday which would’ve been 9DPO and I saw a vvfl, then again today 11DPO expecting the line to get a little darker or at least stay the same and now I see nothing. My expected period should be on Saturday. They were both fmu and both taken with first response. On the test I took today the control line looked kinda bumpy if that makes sense, so I don’t know if the test I took today was defective or what. Does anybody know what could be going on or when I should test again, would it be okay to test again later on today or should I just wait for tomorrow morning?

Edit: in person you can see the color better on the first test that I took so I don’t think it was an indent.

These tests are from Monday the 20th

And these are from today
