I've been doing some reading up on this but I figured I'd see what the general vaginarium consensus is... serious responses only please. So I've read that the depo shot is as effective or even slighlty more effective than a condom... true? From what I understand, the shot is basically good for at least 13 weeks and doesn't get any less effetive during the last few weeks before another one is due... but if one waits longer than 13 weeks to get a new shot, they should abstain or use condoms for two weeks after that to be safe. Correct? My girl is on depo and is due for another one in about a week. I just want to make absolutely sure that it's okay to rely soley on the shot for birth control as long as she continues getting them on time.
