Ultrasound scans are painless but the gel used within the examination can feel a little cold and you may feel a little discomfort when the ultrasound probe presses on your tummy if you have a very full bladder.
An ultrasound scan typcally takes approximately 10 minutes to complete and the images seen will determine whether a Trans-Vaginal ultrasound scan (internal) is needed.
Your ultrasound scan will be carried out by one of our highly qualified professionals in a caring and comfortable environment.
During your scan we will explain the findings to you and following your scan we will give you your images and detailed report.
– At this stage the baby is now much more recognisable as a developing baby.
If the heartbeat is present and the baby measure appropriately for your dates, the risk for having a miscarriage now drops to 1%.
A pregnancy can be seen from as early as 6 weeks from the first day of your last period (LMP) and not the date of conception.
We look at the heartbeat and measure the Crown Rump Length (CRL), this means the measurements are taken from the top of the baby’s head to its bottom.
Early Pregnancy Scans are not routinely offered on the NHS but you may have one privately without affecting your NHS entitlement.
Sometimes it is requested by a doctor or midwife to confirm that your pregnancy is healthy (in this case your scan is often called a viability scan) and to calculate the date when your baby is due (usually referred to as a dating scan).
Early Pregnancy Scans are normally performed trans-abdominally (through your tummy) however an internal (vaginal) scan may be required at earlier gestations ie 6-7 weeks to see all the necessary detail, or if your womb tilts backwards (retroverted).
We will always try to scan trans-abdominally first but if we need to do an internal scan then this will not be harmful in any way to the baby and would be discussed prior to having the scan.
