Could this be pregnancy?

Patient: Hi. I was on the depo shot for 6 yrs and I got off of it about 6 months ago. I have been “feeling” pregnant for a little while now. I have frequent headaches, I feel like I’m going to vomit but i don’t, I have to pee like every two hours, I am hungry all the time. My stomach is hard at the top and it hurts there and in my lower left abdominal area. I have taken home pregnancy tests but they came out negative. Another strange thing is, I have been bleeding and its not a normal period color is brighter and had a clear kind of discharge mixed in it. I was confused of what it might be and was hoping for your input.
