Life after depo shot

Can any of you ladies tell me about cycles ovulation and TTC after the depo shot. I was on it for 3 years and for 2 years it stopped my period. I got off it December 5 and started back on my monthly cycle and the end of January. Got them normally but way more heavy then they use to be. (I know all experiences are different). Just really need advice we have been trying every since December and nothing. Help please
