TTC but it's difficult!!!

I'm 23 no kids but a boyfriend of 3years!💍 I got on the depo shot Nov of 2012 I had a appointment Oct 31,2013. I didn't go while I was on depo I didn't have my period I was told that's normal. January of 2015 is when my period started back lasting a few days then stopped. I only had one 7 day period this year. My period has always been irregular but it usually lasted 7days when I was in high school. I tried detox tea, regular excerse, changing my diet but nothing is working I don't smoke or drink I just have baby fever and I'm ready
