I was on Depo before. I seem to remember my Dr. telling me that this can happen because when your on it your body basically thinks it's pregnant, you don't have a period and what would have been shedded in the normal process just kinda builds up. Then when you go off the Depo the excess starts to come out. I did'nt use it anymore partly due to this reason, I just don't think that it is good for my body. Besides the fact that when I did decide to stop, I was menstruating for 40 days! Yes I said 40 DAYS!! Never again will I ever take that stuff! Sorry about the little rant. Hope this answers your question! Oh, and I would get it checked out if you do get an odor.

Yeah, you're probably not used to seeing a discharge because you aren't used to ovulating. Check back in and let us know what kind of a discarge it is. Does it have an odor?

Is it abundant and kinda stretchy or watery? If so, you might be about to ovulate :-)
