Darker?

So I MC in Feb at 5wks. I tested negative this past Wednesday, and positive Friday. Today I’m 4wks 3 days. My hcg Friday was low at 28, but Dr felt it’s consistent as I probably ovulated later then I thought (I wasn’t tracking opk). Anyway, I go back today to the hospital for labs, but I won’t know anything until Monday. I took another test this morning. I know if you MC you test positive for awhile, I get that, but I was just hoping my line was darker, which i def think it is? Hoping for a sticky rainbow baby this time! Left is today (Sunday), right is Friday.
