Still having symptoms

Almost a week ago I think I may have miscarried, I was bleeding like I was having a period then started to pass blood clots, big ones. I also had cramping but I still feel pregnant? I am still craving certain foods I get nauseous in the mornings, I have weird dreams, my boobs ache and I'm still hungry all the time. Is there a certain amount of time after miscarriage that my symptoms will go away or is there a chance I could still be pregnant. I was 10 weeks and 4 days when all this happened.
