Too early to test or am I out?

Lainey • Due with Baby #1 Nov. 2016!
This is our first "real@ month TTC. I feel silly getting nervous about BFN or BFP so early on when I know there are others who are really struggling.
I'm 9/10 dpo. I just tested using frer after lunch, and BFN. Which was not unexpected really, but my question is now, is that a for sure BFN? Or is it still possible I'm pregnant?
