trigger progression back and forth HELP.

I am sorry for posting everyday. Lol. This is my first and last ivf. I am 5 days past 3 day transfer and 10 days past trigger ( 10,000). I am such a poas addict and wanted to test out my trigger so I knew if the line was real later. It started to fade then came back a bit darker. Now todays is a little lighter again. These are all fmu. Anyone have something similar happen or have any guesses?
