First appointment was today. She did abdominal ultrasound, not transvaginal.. baby is measuring 7 weeks 4 days. Which I think is off because I should be 8 weeks 4 days. Considering when I went to the er and got an ultrasound due to bleeding I was 7 weeks 2 days and that’s been a week ago. I had a new dr that was new to the facility that I go to. Do you think it was cause of the type of ultrasound as to why the baby is measuring smaller
