did anybody experience chemical pregnancy with very dark pregnancy test?

Hi everyone, I am losing it. I had 4 consecutive early miscarriages in the past 4 months and now this. This time the testes look darker compared to he other times. In the picture I tested every 2 days since last week. I am today only 3 days after missing period (last test on bottom) so still early, but I am experiencing a lot of cramping, my boobs are completely normal, no sore, no swollen , nothing, and I have back pain. I don’t have any pregnancy symptoms but rather pms symptoms. Did anybody experience this and had a vital and healthy pregnancy??
