ok so i was on the depo provera shot and i was soppose to get another shot back in December and i missed it because i didn't have the money. So i got my period about one and half to two weeks ago. Well yesterday jan 14th i noticed a small amount of brown bleeding. This morning jan 15th i noticed i had very sharp pains in my lower stomach. Could this mean i am Pregnant. And if so could it show up on a test before implation bleeding? Thanks please answer as soon as possible.
