Pregnant? Time to test?

Ashley
I am curious. I had unprotected sex with my fiancé on the end of October and the 11th of this month. I am not currently in birth control. ( save me the lecture please) 
The 11th was when this app said I was "fertile". I was suppose to start my period on the 27th of this month. I am usually always a day or two early. I have no period symptoms like I usually do. QSleeping at the drop of a hat.... Is it worth it to test now? Or just wait a few more days? Just curious those of you who have been pregnant.... Thanks ladies!
