Hi everyone, just joined the forum and thought i'd ask my first question. I have been with my current girlfriend for about 2 years now and have been very sexually active with her since we first met. She has been on the depo shot for about 3 years before we got together. I'm just kind of curious about the effectiveness of the depo shot. Has anyone ever got pregnant while on it? Missing an appointment for the shot and getting pregnant does not count. I'm talking with regular visits every 3 months. We have never used protection other than that and she gets tested for SDS's and such every so often. Just wondering, thanks.
