Line is getting lighter

Janel • 41 y/o FTM trying to figure it all out
My family is getting tired of me obsessing, so I'm turning to the ladies here who have a little bit more experience. I'm 39, TTC # 1. I finally got my BFP on 8 / 26 (1st day of missed af), and I had confirmation with the digital. However, my doctor can't see me for a blood test until Monday, so I tested yesterday and today to see if my levels went up. It looks like the line is getting lighter. I've had intermittent cramping and no spotting. Does this look like a chemical pregnancy to you?
