I would say be patient,
I applied within the country for the federal as I did my process with AINP
December 1st 2017, mailed my doc on paper to Sydney Nova Scotia office
Got my medical in May, résults that I passed two weeks later
And I have been waiting same like you since then
I am sure there is nothing wrong with your application we just need to have some patient, I know we have different cases but we might get it at the same time, I would think we will be hearing back by feb March next year!
Hopefully you hear back before that
Happy waiting
