So I know it's a different kind of test but if it helps at all, here is my Wondfo progression with a beta. My 11 DPO lines started off quite light, as you can see, and darkened just a tiny bit throughout the day. Hope this helps. I will try to track down my FRERs too.
ETA: 11 DPO FRER added too
I think your test looks great. Everyone's hCG is going to be different, so I wouldn't worry about darkness by DPO, but rather from test to test, whether the line is getting darker. The line is definitely there and it's definitely in the range of normal for 11 DPO!
