Does depo shots make it hard to conceive

La'Shonda
I've been off depo for a year and I've been trying for a while to conceive and no success. I had a friend who was on depo when she was in her teens to early 20s and now she's in her late 20s and it's had to conceive. I was only on depo for like 6 months and I just hope that didn't make it harder for me to conceive. Any advice?
