Life after depo

Hello! I am new to this site so I apologize in advance if I don't have the lingo down correctly. After entering a relationship summer of 2013 I immediately got on depo. Before that I had naturally irregular periods, one to three a year. After starting depo I starting bleeding randomly and every time after sex. My periods became erratic and we're only a week or two apart. In November of 2014 was my last depo shot. I continued to have random periods that lasted roughly two weeks every month. As of June 2015 I have not stopped bleeding. I was told that this is normal. My partner and I have decided that we want a child. We have not used any sort of protection since getting off depo. Has anyone else had similar trouble with depo?
