Tests

I know I shouldn’t keep testing but I’ve had two miscarriages this year and sometimes testing gives me piece of mind. The top test was taken Thursday at 22 dpo and the bottom was taken today (Sunday). The top test was a dye stealer and three days later the line looks to be getting lighter not darker. I am five weeks four days. Anyone else have a similar experience? Only reason I can think is my hcg is decreasing. I’ve noticed a loss of symptoms too. Boobs don’t hurt like they did last week! I know the only real way to know is blood test or ultrasound.
