Need some reassurance

I tested on 8/9 and got a vvvfl but I can see pink in person so I tested again yesterday with fmu and same thing i got another vvvfl but pink in person.

Well today i tested with fmu but it looked diluted(i drank alot of liquids yesterday) and could barely see a line..well i tested again with smu and I was negative,,, idk what to believe..

Maybe I'm having a chemical, imma call to get blood work done today

Im 8 days late but I think i ovulated late
