Depo was "invented" for those that never really wised to get pregnant again. It was supposed to be the "cheap" version of a tubal ligation or a vasectomy. But we of course aren't really told that. Just like tubals or V's many will tell you not to make the decision after you've given birth or while you are pregnant, because they know you will change your mind as time goes on.
In some aspects Depo can wear off but the time it takes and the heartbreak it can cause is a lot more than some can handle.

yk?!
