Background Check status not changed (Express Entry PR)

Hi, I submitted my application on May 8th and on the same day I received the e-APR. Medicals passed on June 6th. But since then the Background Status is 'Your application is in process, we will send you a message when we start your background check'. Anyone has any idea if my background status has been started (IP1) or not? It has been more than a month that the status is like this. Initially the status was 'Not applicable'. I would appreciate if anyone can answer my concern..
This is ip1 .. I am on the same stage from last 2 months. My AOR is 20 april 2017.. I dont know as well.. What they look in ip1. R u still.on the same point?
