You can but it is very hard. Most of the time you will not see a pregnancy if you are not having some kind of a cycle.I took the shot too and after stopping my OB had to give me something to jump start my cycles again. When my son was 3 I had my girl. I sounds like you may want to tell your doctor about the no cycle and let them help you with getting back on track if you are wanting to try for a baby. With out having a cycle you are not sure if you are Ovulating and if so when. Knowing when you are Oing and if you are is the key thing to trying for a little one. I wish you all the best.
