I'm six weeks pregnant and starting Sunday my morning sickness has gotten progressively worse. I feel sick all day even after vomiting. I haven't been able to hold any food or drink down. I've tried crackers, toast, and ginger ale. I've even tried pressure points. Nothing helps. I've lost 6 pounds in three days. Do I need to see a doctor about this or is this fairly common. Also is it going to get worse since it's so early in?
