as a mother of 4 with my 5th on the way please know that you have to be patient. typical ob's will order an ultrasound at about 15-20 weeks. truly other than a heart beat and some newly formed limbs. an ultrasound at 6 weeks doesn't give you to much info other than if the baby is developing normally and accurately determining a due date.
how early can you tell gender? . using a 3d ultrasound how early can you tell the gender of your baby? can you tell at 6 weeks along?
