Questions on my birth control

Melanie
 Hey everyone I'm new to this group but I have a quick question.  This past June made a year since I've been in the depo shot. I had a period match of 2015 and a one day period in April but have not had one since then.  Now being September I'm finally been cramping and breaking out but me and my fiancé are trying to conceive and have been since May. Any advice on how long it will take? Or what I should do?
