BFP with dark bleeding

So on 9/29 I took a frer test and got a faint positive.

Two days ago on 10/4 I started out with light spotting that's now turned into dark red blood, almost like a period but not as heavy, with lots of little tiny clots and stringy parts. Been using 2-3 liners a day but they don't fill up completely, I just like to keep it clean. Called my doctor and they drew my blood Friday (10/5) but I won't know anything until Monday (10/8) (since they're closed on the weekend and everything 😔)

This morning on 10/6 I took another pregnancy test.

It's just as faint as the one a week ago. I'm not sure what to think. I'm thinking it's probably a chemical as I'm only suppose to be 5 weeks 3 days today. What do you think?
