How long after getting off depo did you get your period?

How long were any of you off depo before getting your period. I got 2 shots of the depo so was on it for 6 months and have been off of it for 3 weeks and still no period or bleeding (i had constant spotting during the shot) as soon as i didnt get my next shot my bleeding stopped and a week later lightly spotted one day and then never again. Just wondering, i get cramps some days but nothing ever comes from it
