Looking for some advice

I was taking the depo provera shot from February 2009 till august 2015. I haven't taken any kind of birth control since and still haven't had my period yet. I already know I'm not pregnant because of the lack of sex between me and my fiancé (once every few months) and I've been taking pregnancy tests throughout this entire time to make sure. I know it can take up to 11 months for my period to come back but it is now pushing it close to that time frame. Any advice on what I should do? Should I wait it out or go see my Family Doctor? I'm trying not to go back to birth control for a while seeing that I feel it's a contributing factor to my depression and very very low sex drive.
