TTC Post Depo Shot

Hi Everyone! 
I stopped taking the depo shot last January (2015) and from December 22-25 I had some bleeding, which I have been determining was my period starting again. My husband and I are TTC. I have been taking prenatal vitamins and have done all the pre-pregnancy screenings and tests at my OBGYN. Has anyone else been TTC after depo? Any advice is appreciated.
