Baby Dating Ultrasound Scan
A baby dating ultrasound scan is useful if the dates may not be correct due to having an irregular cycle or if you did not know you were pregnant and can’t remember when the first day of the last period was.
The age of a pregnancy is calculated from the first day of the last period (LMP), this means at the time of conception you are already 2 weeks pregnant! By 5 weeks from the first day of your LMP on scan it should be possible to see a pregnancy sac usually with a yolk sac present. Then by 6-7 weeks there should be a fetal pole and fetal heartbeat present. The age of the fetus is determined by measuring Crown Rump Length (CRL), this means the measurements are taken from the top of the baby’s head to its bottom, from this measurement we can work out how many weeks and days pregnant you are.
If the pregnancy is very early then it is usually necessary to do an internal (vaginal) scan. If the pregnancy is more than 7 weeks it may be possible to see enough abdominally (tummy scan), sometimes both scans are necessary to ensure all is well.
During your scan we will explain the findings to you and following your scan we will give you your images and email your report to you. If we feel that any follow-up is necessary, we will advise you regarding what is necessary and how to arrange further assessment. Please be aware that if your pregnancy is not progressing as planned or if an abnormality is detected during the scan, the results will be discussed with you immediately following your scan and a plan of action advised.
Please note: Our scans do not replace the routine NHS monitoring scans but are provided as a service for additional reassurance.
