Heartbroken

I posted my test on here last week and everyone agreed it was definitely positive. The line actually got darker up until yesterday when it went almost obsolete. I called the doctor today to do a blood test. She called and said the urine test was negative and my blood test was only 5.6 and if I don’t start bleeding soon to wait a week or two and take another test. I feel like an idiot or something 😔 I also feel like it was a chemical, even though she didn’t say that...but I just don’t know.
