About 3 or 4 months ago, i began taking the depo shot. Since starting, I have had no bleeding, period, pain, etc. Tonight, I noticed irregular bleeding. I have been having lower abdominal pain, burning/hurting when urination, frequent need to pee and hardly any coming out, an irregular amount of clear discharge and i also have a slight odor - kind of like bread smelling. I've heard it could be anything from my body adjusting to sweat (since i just started a gym membership) to having an STD. Any ideas?
