Am I miscarrying?

I'm about 6 weeks today, I found out exactly last week that I was pregnant. I had bloating and light period cramps all week, but today i woke up and i just "didnt feel pregnant". In the first picture, the 3rd test is the darkest and I took that one on Tuesday, I just took this one (2nd picture)

and it seems like it's gotten lighter.. can someone provide some insight? I dont have health insurance at them moment and I called my local clinic and the 1st prenatal appointment is $1,000. I've had no spotting or bleeding. 😕
