12 week dating scan what is a safe dating site
Although sometimes known as the reassurance and viability scan, your 12 week scan is more typically referred to as the dating scan.
Bear in mind that you may not have your scan at exactly 12 weeks; it usually takes place between your 8th and 14th week of pregnancy.
You should then see the black-and-white image of your baby appear on the screen.
The clarity of the picture depends on a number of things.
If you’re waiting until your first scan to share your news, you might feel like 12 weeks can’t come soon enough.
Learn why the dating scan is carried out, why your due date might change, and get tips to help you prepare for your appointment.
You will have had earlier appointments and may have had an early scan if you've had any concerns such as bleeding, but otherwise this is the first time you'll get to see your baby, so it's a real milestone in your pregnancy.
Before the scan you will be asked to drink a lot of water and have a full bladder, as this puts the uterus in a better position to be scanned.
The NT scan measures the amount of nuchal fluid at the back of your baby’s neck because babies with Down’s syndrome may have more fluid than usual.
It’s non-invasive and simply a case of the sonographer getting a good enough view of your baby’s neck to take a measurement on screen.
The dating scan is usually done at some point between 8 weeks and 14 weeks pregnant.
NICE recommends it's done between 10 weeks and 13 weeks.
