Hello I am 20 yrs old and I have been off for six months. I have had brown discharge two weeks ago. I have several pregnancy symptoms. Sor nipples/breasts, urination a lot more, cramping, tired, more hungry, back aches. I had negative pregnancy tests a week ago so I'm confused as to when to take a test or what is going on with my body I don't see how I have all these symptoms from depo since my last shot was last December 2011. Anyone have info?!
