Hi my name is Brittany. I was on Depo Provera I took a shot my first shot in October and I was due back in December. But I did not go I missed my period January 19th and I missed my second period February 16th. I took pregnancy test but they came back negative. I have tender breast, I been gaining weight, headaches, urination a lot, some stomach pain, I only really been craving nachos and boiled peanuts; I do put honey on some certain things. Also I been a little emotional one minute happy next minute sad, sometimes mad. Could I be pregnant but my hcg level be low? I'm confused.
