Measuring baby is small

Melissa

Went for our first ultrasound today

I'm 12 weeks & 4 days but they said I'm measuring at 11 weeks. Is that bad? Got to hear the heart beat & see the baby but I told them it is my first baby & 1st ultrasound & they rushed us in & out. I know nothing about babies or ultrasounds. It was suppose to be a special moment ☹ and they made so impersonal. But we have a picture of baby! Going back in two weeks to check on the size of baby
