8DPO and seeing things

Told myself after over a year of unexplained infertility and loss I would wait until I actually missed my period to take a test. I am 8DPO and decided to take a test this evening after getting home from vacation since I’ve been experiencing lower back pain, mild cramping, and some nausea over the last three days. My husband doesn’t see anything-does anyone else see what I see?? I will of course be testing again tomorrow first thing to see any change.
