MC 6weeks test still very dark

Je

Just wondering if anyone has any experience or advise, I had an early miscarriage last thursday so 1 week today. I would have been just short of 6 weeks along, I only bled for 24 hours period type flow with a few clots just tested today I know it take 2 sometimes 3 weeks to get a negative test but just wondering if it’s usually still this dark a positive at this point?
