Wtf is wrong with me?

So I was on the Depo for a year, came off it August 2016, had periods come back and had 3 between May-July 2017, then nothing. Until August and September I had a few days of dark funky yuck ness I assumed was my body’s attempt at a period. Now I’ve been moody as helllllll, occasional sore boobs, major cravings and green poop? Negative tests aswell. I’ve been to the doctors and they both just said I had to wait it out until my body decides it wants to work again. Can anyone help me!!?
