TTC after being on depo shot for a year

Hey ladies!! I'm new to glow. I was wondering if anyone on her TTC after being on the depo shot. I was on it for a year. Last June my husband and I decided to have one more (he'd like 2 more). My last shot was due in June. I finally got my period a few weeks ago but it was really light. Was that considered a period? How long did it take you to conceive after being on the shot?
