Confused inconsistent pregnancy test lines

keno

Hi there I am so confused and am wondering if anyone could help or has experienced anything similar. I have been spotting for about 4-5 days light brown and AF is due tomorrow. I felt off 4 days ago and did a first response test which had a vvfl. I tested the next morning and it was basically gone. I figured I had a cp but something told me to test again, I have tested each day around 1 pm and I get a positive result and today it was very positive so I went in for a blood test which I will get results from tomorrow. Please help!! What is going on? I have 1 daughter and have had 2 mc, each time my tests always got darker once I had the first positive. It’s making me so nervous.
