At 13 weeks, the anatomy of your baby can be assessed in great detail. Technology has advanced significantly and we can now recognise or suspect any structural abnormalities at 13 weeks, these checks are best identified via an internal ultrasound (ideally performed between 12 weeks 5 days and 13 weeks 2 days).
What type of ultrasound is done at 13 weeks?
Nuchal scan. This scan is carried out from 11 weeks to 13 weeks and six days. The scan is usually performed transabdominally but in a few cases it may be necessary to do the examination transvaginally.
Will my 13 week ultrasound be transvaginal?
The cervix is routinely assessed at both the 12-13 and 20-22 week ultrasounds. This is usually done abdominally. If the cervix appears short, a formal measurement will be performed with a transvaginal ultrasound.
What can I expect at my 13 week scan?
This scan will also check the fetus generally for abnormalities. The following structures will be checked: head spine, body, stomach, bladder legs, arms, hands and feet. It is important to note that abnormalities of the heart, kidneys and face will not be obvious at this stage.
Can you tell the gender at 13 weeks?
The accuracy of determining your babys gender increases with how far along you are in the pregnancy. The accuracy can vary from 70.3% at 11 weeks to 98.7% at 12 weeks, and 100% at 13 weeks. Eleven weeks is the earliest that sex determination can be carried out with an ultrasound using a method called the nub theory.
