I girl has to take the shot every three months and she was on it for over a year ( she was dilagant on keeping up with the shots )... While you are on the shot... U don't have your period.. But yet.. she got knocked up.. Sadly she had a miscarage but it was still unplaned.. we want to wait untill we were older before we had kids... She is back on the pill and I am using rubbers everytime now.. BE VERY LEARY WHEN ON THE SHOT!!!!!
Depo-provera has a low failure rate, but like any method of birth control, it's not zero. There's always some possibility of failure. If you really want to be safe, it's not a bad idea to use a condom in addition.Also, Depo has the side effect in some women of demineralizing the bones, which weaken them. It may be even more of an issue for adolescents and young women, whose bones are still forming.(By the way, "knocked up" is a pretty crude phrase for "pregnant".)
