12 week dating scan expect

Sometimes a trans-vaginal examination shows that your pregnancy is less advanced than expected.The earlier the ultrasound is done, the more accurate it is at estimating the baby's due date.However, the accuracy of the ultrasound examination is always dependent on the skill of the sonographer and the quality of the equipment.

For transvaginal ultrasound you can have an empty bladder Dating scans are usually recommended if there is doubt about the validity of the last menstrual period.

For example if you a tiny sac can be seen in the uterus, but the baby and its heart beat may not be detected yet.

Before you go for your scan, you’ll be asked to drink lots of water and arrive with a full bladder.

This can be a bit uncomfortable if you have to wait with a full bladder but it does put your uterus in a better position for scanning.

• Find out if the baby is growing in the right place • Find out if you’re expecting twins, triplets or more!

• Check your baby’s general development including their heartbeat, limbs and some organs • Other potential abnormalities including spinal bifida • Most hospitals will be able to sell you a copy of your scan photo for a few pounds or ask for a donation Most units will offer you a screening test at the same time.

The sonographer will then use a transducer device which uses ultrasound to produce an image of your baby inside the womb to a small display screen next to you. The dating scan is the first time you (or anyone) will have seen your baby so there’s a few things that your sonographer will look out for and things you’ll find out: • How many weeks pregnant you are, and your EDD (estimated date of delivery).

This will be a lot more accurate than working it out just using the date of your last period.

The dating scan is non-intrusive and won’t be painful; in fact, it can be quite a relaxing and exciting experience to see your little one and their tiny heartbeat for the first time.

The process will involve lying back on a bed, with gel applied to your belly.

If you have any questions about this, please feel free to talk to your sonographer or doctor about it.
