TTC after depo

I was on depo for a year from 2012-2013. My last shot was the end of June 2013. I still haven't gotten my period, but last month had a dark brown discharge (sorry for Tmi). I ordered fertilaid to help balanced hormone levels. Have any of you ladies used it? How long did it take to get or regulate your period after starting it? My husband and I want to start TTC when he gets home from his deployment. Any help you can give would be greatly appreciated. Thank you in advance!
