BFN at 10dpo

I'm so frustrated. My first was unplanned and it was a fluke that I took a test 6 days before my period was due because I was I just felt off and was paranoid. This was our first month not using protection since his birth and according to this app we dtd twice in my fertile window. I'm sure this is too early to be sure, but after getting a positive so early last time I feel like I'm out for this month. Didn't think it would bother me, but it is. :( anyone in the same boat?
