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.
If you have had any bleeding or pain or any other symptoms then this scan will accurately confirm viability.
At around seven weeks of pregnancy, it’s reasonably common for women to have their first ultrasound.
This can be for many reasons but the most common is to confirm pregnancy and to check that the embryo is viable and “everything’s ok”.
It’s time to clap your eyes on that baby for the first time and it’s the most exciting pregnancy milestone yet. Your 12-week scan can take place any time between 11 and 13 weeks.
An average length of the embryo at 7 weeks is anywhere between 5mm-12mm. Obviously, every pregnancy is unique and individual factors influence the size of the embryo at this early stage, and the embryo shows development week by week.
But, assuming your pregnancy is healthy, you'll still have the dating scan at round about the 12-week mark.
The scan is done externally by rolling a device over your tummy (unless your womb is very deep in your pelvis or you're very overweight, when it may be thought better to offer you a trans-vaginal scan instead). This is because, as immense explains, "If you drink lots of water beforehand, you get better pics: it pushes the uterus (womb) closer to the surface!
Although the sex organs are well developed, it's usually too soon to see them at 12 weeks.
Some people believe in nub theory, which suggests you can determine the gender of your baby from that first ultrasound photo. We know how exciting/terrifying the whole thing is, but too much anxiety and you’ll be jumping off the bed as soon as the gel touches your belly (it’s very cold).
