Went from dye stealers to normal tests is my hcg fading?

Mama Constantine

Ok so I’m only 7 weeks first ob appointment is in a few days. When I first started testing I got dye thieves consistently on strips and sticks. My best friend and I found out we were pregnant a week apart. She miscarried so I freaked out and started testing again when I first wake up. Top 3 tests are the dye stealers from 3 weeks. Bottom 3 strips are last 3 days with first pee of the day. I know they’re + but should I be worried that my hcg is seemingly dropping?
