Coming off Depo Provera

Was wondering if anyone else is confused about what happens after you get off the depo Provera shot. I have been off the depo since the end of April, I just had my first period at the beginning of this month. I find myself EXTREMELY emotional. On top   Of that I recently had heavy spotting, or maybe a light period again. Not sure if my ovulation cycle is what it should be because I bleed again. I would like to become pregnant soon, but have read numerous stories about miscarriages after the depo. If anyone has any info it would be appreciated.
