Getting off Depo & Wanna Get pregnant

I have a Question.... I started my Depo shot March 16 2018, And my last shot was August 9th . I am suppose to get another shot on October 25th but I didn’t because i’m trying to get pregnant and now i’m only 4 days late ... Do anybody know how long it will take? Or if the depo is out of my body? I need information on this, I tried google but it didn’t answer my question .....
