Help, 7wks post MC, Pregnant?

Ok so, I’ll post photos for reference, and I’m seeing my doctor tomorrow. But I had a miscarriage at 8wks, 7 weeks ago. I had been tracking my test line getting lighter with cheapies. I’ll post a picture of the cheap test being practically negative, with a test underneath that looks slightly darker taken the next day. A different cheap test taken today that to me looks even darker and a first response test. Should it even be this dark 7 weeks after? Could I be pregnant again? Never had a period after the miscarriage..
