Quoting Addi's Momma:" It can make you infertile. My doctor refuses to give it to women who want to have children in the future. ... [snip!] ... reasons after depo. I think more doctors should be giving out advice like this instead of giving the shot to everyone."
I herd about that too that it makes you infertile.
Alot of doctors don't tell people about it though which is messed up.
Now when I hear my friends or family talking about getting on that I always tell them not to, to choose something else and do reaserch before they go get B/C
