Had an untrasound done today what we originally thought was 6 weeks 1 day, looks like 5.5wk, gestational sack, and yolk sack present. HCG was 3849 on Monday, today HCG is 3772, not a big drop but still a drop. No one seems worried about this but me. We are doing a 2nd untasound in one week. With the drop in HCG could it be a miscarriage, or is the normal ultrasound, and no miscarriage symtoms more important?
