Depo shot

So last year I was on the Depo shot and it was great and effective. But I got off of it in January because my bf broke up with me and I wasn't having sex. lol but now it's July. Seven months have gone by and I still don't have my period back. I'm starting to get worried because there hasn't been any signs of it coming back. I am about to move out of my parents house and have started talking to someone so I would like to get back on birth control but I don't know what to think about not getting my period during these months. Your thoughts?
