Have any of you spotted at 5 weeks (15dpo) and had it not be a miscarriage?

Er

I had a mmc at 9 weeks in September.

Chemical last cycle.

This time I have gotten dark positives and all has been good. Just wiped and saw a tiny bit of light pink blood. I'm concerned because I feel like the darkness of my tests indicate that implantation has already occurred and now I am in full panic convinced I'm having another miscarriage.

Anyone been through this?
