Worried

So I am seven weeks pregnant. So far this pregnancy I’ve gotten bad news at each appointment. Not tremendously bad like I am miscarrying again, or anything. Things like subchorionic hemmoraging , threatened miscarriages, low heart rate for the baby etc. I noticed today, and most of yesterday that my symptoms have kind of disappeared. I don’t feel nauseous anymore, I don’t feel tired all day long, my boobs don’t hurt. The only symptom I have is extreme hunger. I have been so hungry this last 24 hours. Should I be worried? I don’t remember if my symptoms ever randomly went away with my kids.
