Looking for opinions

Katie
First off I know that all the "could I be pregnant" posts can get old but I'm going crazy. 
​backstory: My DH and I were not tracking anything or timing our BD with ovulation we were just letting it happen if it happened but recently we have started paying more attention to my cycle.  
​So I jut started using this app and tracking temp and cm and all that jazz.  So all I have to go off of for my O and fertile window this last cycle is the projected dates. We BD 2 days before my window started and now I am 12DPO CD33 and 3 days late for AF. Could I be preg or am I just late/irregular?
