Found this today and thought some might be interested to read it xx
What can you expect to see on your early pregnancy scan?
5 weeks pregnant:
A small gestation sac in the uterus measuring approximately 3 4 mm
6 weeks pregnant:
Within the uterus a small gestation sac and maybe a small yolk sac within it can be seen. Closer to 7 weeks a fetal pole, the visual start of seeing a baby(s) but still measuring only a few millimetre (the size of a grain of rice) with a heartbeat the chances of pregnancy continuing 78%.
7 weeks pregnant:
The baby usually measures 10 20 mm and a heartbeat can be seen clearly
8 weeks pregnant:
Baby now measures 20 30 mm and again a heartbeat is clearly visible. Chances of pregnancy continuing 98%
10 weeks pregnant:
Baby now measures 35 40mm and if the heartbeat is present and the baby measures appropriately for your dates, the chances of the pregnancy continuing is 99.4%.
11 weeks pregnant onwards:
The baby is now measuring approximately 45mm and clearly has a distinguishable head, body, arms and legs. The heart can be seen beating in the chest area and the stomach, bladder and cord insertion are visible. The baby from this time onwards just has to grow and get bigger and stronger.
For many expecting mums who do not want to go down the route of screening for a chromosomal abnormality such as Downs syndrome then this scan can be performed to give reassurance that all is well up to 18 weeks of pregnancy.
What do we check for on the early pregnancy scan?
The dating pregnancy scan performed between 6 18 weeks will confirm:
That a gestation sac is seen within the uterus i.e. the pregnancy is intrauterine, growing in the womb and not ectopic, i.e. growing outside the womb.
The number of babies you are carrying.
By 6/7 weeks in pregnancy it is possible to detect the babys heart beat(s)
We measure the babys head (crown) to bottom (rump) length (CRL) allowing us to determine how many weeks pregnant you are.
After 14 weeks in pregnancy the babys measurements change, we now measure the head circumference (HC), abdominal circumference (AC) and femur length (FL). We change to these measurements as the baby is now curling and the CRL measurement becomes inaccurate at determining gestational age to date the pregnancy.
From 11 weeks the babys head, body, arms, legs, stomach, bladder and cord insertion will be checked to rule out a large number of major structural abnormalities including anencephaly, gastroschisis, exomphalos and megacystis.
