Depo shot effects...

Shandon
I had a baby unexpectedly in November 2015 and got on the depo shot in January at my 6 week postpartum check. I got my first period after getting the depo shot, and I had it for 2 and a 1/2 weeks!!! I don't know if it's the combination of having a baby and the depo shot but is a period that long, normal??? I still had my period while pregnant btw
