I had my first appt today!!!

Got to see our baby today! As soon as the baby came on the screen it was moving so much then stopped lol. But heart rate is 155 and I am suppose to be 9 wks 5 days according to my last period. But she said I was measuring a week a head but didn’t change my date? Did anyone else have this happen. I was so excited I had to share my little gummy bear with you all 😍
