A dating scan is an ultrasound examination which is performed in order to establish the gestational age of the pregnancy. Most dating scans are done with a trans-abdominal transducer and a fullish bladder. If the pregnancy is very early the gestation sac and fetus will not be big enough to see, so the transvaginal approach will give better pictures.
We at MUMS understand that the first few months of pregnancy can be quite an anxious time for many women with various concerns as to whether the pregnancy is developing normally or that it may result in a miscarriage or even an ectopic pregnancy. An Early Pregnancy Scan sometimes also called a Viability Scan or Dating Scan provides reassurance in this very early stage of your pregnancy. 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.
So just what does happen at the week scan? Your week scan can take place any time between 11 and 13 weeks. So you can see all his organs, muscles, limbs and bones are in place, and the sex organs are well developed too.
A pregnancy can be seen on a scan from 6 weeksbut usually your first scan will be offered at 12 weeks. However, there are reasons why you might be referred for an early pregnancy scan, sometimes called a dating scan or viability scan. Why you might have an early pregnancy scan You may be offered an early pregnancy scan if you are experiencing bleeding and spotting in the early stages of pregnancy.
Unless there are concerns about the pregnancy it is better to wait to have this scan after 7 weeks as the images are clearer for you to see and better for us to measure. If you come before 7 weeks the baby will be less than 1cm in size and so the scan sometimes has to be performed transvaginally placing the probe inside the vagina to enable us to see the baby well enough to measure and to see the heartbeat. We ask that you come with a full bladder for this scan as it usually allows us to get the best possible picture of the baby.
