Shouldn't they be getting lighter?

I asked in another group but didn't get any response.

I miscarried twins on 10-23. Two weeks ago today. Due to scheduling conflicts, I only got to se my dr yesterday and they did take blood to check my levels, thyroid and to see if I'm anemic. I'm still waiting to hear back. They asked about pregnancy test and i told them they're still really strong positive. I did one in the office before my doctor said he wanted blood. I mean, is this normal? I really just want to be done with it all so I can move forward. It's been a really long year and I'm tired of doctors.
