It's not over until the blood test results are in...
I was going to say that all the lines look pretty similar to me, not getting lighter, but also not getting much darker either.
For me, I refuse to test with anything but FMU, just so I can't reason with myself saying "oh, but it's not FMU so maybe it would be a line/darker if I used FMU" and all that jazz that goes along with POAS analysis
Still sending sticky baby vibes your way!!!
