Are my lines progressing ok?

I know I’m still early. They go top 2 11DPO, third is 12DPO and bottom is today 13DPO. I’m just nervous because my FRER today was lighter than it has been.. I’ve been using these strips too and todays (bottom) seems darker than yesterday’s and i used the same urine for the FRER but it was lighter? Do you think maybe I just didn’t use enough urine (or too much) on the FRER?

Also I’m going for my blood test now ... has anyone ever had positive urine and negative blood?
