By the time you’re due for your first routine ultrasound scan in London at 12 weeks, your baby will already have grown a lot. From just a single cell, he or she will have grown into a tiny foetus that already looks very much like a baby. You should be able to recognise the head, profile and limbs of your baby, although it could take you a while to get used to the way the black and white ultrasound picture looks.
Your Baby at 12 Weeks
At 12 weeks, your baby will be about the size of a small lime. He or she will be about two inches long and weighs just half an ounce. Although you’ll be able to make out your baby’s arms and legs, the skeleton hasn’t developed fully yet. It is still made out of tough cartilage rather than bone, which will only just be starting to form. Even so, your baby will already be quite active. You may spot some movement on the monitor, although you probably won’t feel anything for a few weeks.
What You Won’t See
Although your baby will be looking almost fully formed at 12 weeks, there are some things you won’t see. The scan can’t provide a picture of your baby’s face as the ultrasound only picks up the profile. You’ll have to wait until he or she arrives or until you can have a 4D ultrasound in London later in the pregnancy. It is also impossible to tell the sex of your baby at this time, as both girls and boys just have a small “nub” where the genitals will form.
It’s also important to remember that if you have your first ultrasound in London a little earlier or later than 12 weeks, your baby will look a bit different. Babies are changing a lot at this time, so even a week could make a big difference in what you see.
