Did anyone’s tests get lighter after the first and kept the pregnancy?

I got an obvious positive at 12dpo with evening urine. 14dpo I took another test with 2nd urine of morning and it was way lighter but there was still a line. Then took another test just a bit ago (still 14 dpo) with evening urine and the line is barely there at all. I’m so scared 😭

Update- I tested this morning with fmu and it was completely negative ☹️ I will call dr on Monday
