Testing out trigger looks hopeful

I took a trigger shot 12 days ago and have been testing it out since 7dpo or 9dpt. The first test showed a very very light positive - what I'd expect when testing out the hcg. The next day it seemed a little lighter and on 9dpo it was only visible if I tilted the test a lot. Today is 10dpo and 12dpt and the line is significantly darker. Please tell me I'm not crazy. My husband says he wants to see something more definitive lol.
