Ladies I'm freaking out

Brittany
I'm on the depo shot. It has already made me have crazy periods. But now after my third shot milk is coming out of my boobs. I had my son back in January of 2015. I did breast feed him but milk supply dried up when he was about 6 weeks old. Could the depo cause me to have a hormone imbalance and that's why milk is coming out of my boobs?
