Here are some things you can probably expect at your week ultrasound. I recommend dressing comfortably, particularly in comfortable pants and a top so the technician has easy access to your belly.

This helps lift the uterus so the technician can get a better view of things. Not a fan of chugging water?

At around seven to eight weeks , the sonographer can confirm the gestational age your due date , plus or minus three days. Your doctor will continue to use this date as a marker throughout your pregnancy, says Kinnear. The technician is looking at whether the embryo implants in the uterus. If it implants outside of the uterus, this indicates an ectopic pregnancy, which happens when a fertilized egg implants in the fallopian tube or somewhere besides the uterus.
Where the embryo implants is also important as it can be higher or lower in the uterus.

There are many reasons for having an ultrasound at this stage, but one of the most common is to screen for one of the congenital chromosomal abnormalities — Trisomy 21, otherwise known as Down Syndrome. This means that there is an extra chromosome — 21 contained in every cell of the body. People with Down Syndrome have physical and intellectual disabilities. Older women are more at risk of having a baby with Down Syndrome.
When a woman is around 12 weeks pregnant her risk of having a baby with Down Syndrome can be fairly accurately assessed. First trimester screening for Down Syndrome can be done with a blood test between 10 weeks and 13 weeks and 6 days.

This can be measured in an ultrasound done between 11 weeks and 13 weeks and 6 days.
A foetus with Down Syndrome has a measurement which is thicker than in those who do not.
