Too early to test?

So, I had unprotected sex 11 days ago, is it to early for me to test? It was the beginning of my fertile window. I have been feeling different than usual.. I am just scared to test. I feel like it will never be positive 😩 My husband & I are currently ttc but this month we could only do the deed once at the beginning of my fertile window and the last day of my fertile window, so I kind of feel like it's not gonna happen this month. Should I wait to test or what? Would it be to early?
