  • What happens during the scan?

    The very best time to accurately date a pregnancy is between 11 weeks to 14 weeks. But sometimes you may find that for whatever reason you may be further on in your pregnancy then you imagine. We can confidently date your pregnancy up until 18 weeks gestation.

    We can do this by measuring the baby from head to bum. The medical term for this is Crown Rump Length (CRL). We will be able to assess if the baby’s measurement is in line with your Last Menstrual Period (LMP).

    If we find that you are a little further on in your pregnancy then 14 weeks gestation but under 18 weeks we can then date your pregnancy by a special head measurement across your baby’s head which is from ear to ear called a Biparietal Diameter (BPD).

    Also during this scan we will check the anatomy that can be seen at this stage & share this information with you during the scan. We will check the heart is beating & listen to the sound of this, this may be the first time you have heard this.

    If we find that your baby measures more than 6 days difference to what your LMP (Last Menstrual Period), is showing us then we would advise you to change your EDD (Estimated Date of Delivery), dating you by Ultrasound Scan (USS), this is a standard national policy upheld in all NHS & private Ultrasound clinics.

    Remember our sonographer has a background in Midwifery, so any questions you may have regarding your pregnancy, she will be happy to help answer!

  • Did you know?

    At 12 weeks gestation the baby is fully formed. He or she will now have all its organs, muscles, limbs & bones. At 11 weeks your baby will measure 45mm & at 14 weeks the measurement is 85mm. Your baby will be more recognisable during this stage, rapidly developing even possibly starting to suck his or her thumb! By now the swallowing reflex has been mastered, you can see this happening sometimes during the scan. Your baby will now weigh approximately 6 grams at 14 weeks gestation. Your baby can be very active from now on.
