No period

Kaila
So my son will be 2 next month. My last period was December of 2012 (right before I got pregnant). After I had my son I waited the 6 weeks to start on BC. I chose depo because I never had a problem with it before. February of this year I stopped going in to get my shot because I got married and we were going to try for another kid. It's been 6 months now and I have still yet to get my period. I'm not pregnant. Sadly, I am also separated. I'm not stressed. I stay active. Should I be worried about not getting my period yet? Usually I get it after a month or two.
