It may take awhile. Even though we weren't exactly planning it it took us awhile for me to get pregnant (we weren't using condoms) I had mine out for about 9 to 10 months before I got pregnant with my twins
@daniellewinfield17 don't feel bad I didn't know either. I had depo before I got pregnant with my first child. Had it like 2 years didnt go back for my shot in like June 2013 and got pregnant November 2013
