A transvaginal ultrasound is usually required to see the baby at this stage of the pregnancy. Although the ultrasound may see your baby, it measures only a few millimetres long, and it is too early to always detect the baby’s heartbeat.
You should not be concerned if we cannot see the baby’s heartbeat at this early stage, as this can be normal.
We usually get better images during transabdominal ultrasound if the bladder is partially filled, so to help your examination we ask you to drink water prior to the assessment.
Please empty your bladder 1 hour before your appointment, drink 2 glasses of water and try not to empty your bladder again until after your appointment.
The yolk sac is the other structure that is usually identified at this early stage.
The yolk sac lies within the gestation sac and looks like a little round circle inside the pregnancy sac.
A first trimester ultrasound will usually include each of the following components however some ultrasounds may focus more on particular areas.
If your bladder is very full and painful, you should empty a small amount so you are more comfortable.
You will be able to empty your bladder after the transabdominal ultrasound is completed and before the transvaginal ultrasound begins (if transvaginal ultrasound is required).
A small amount of ultrasound gel is put on the skin of the lower abdomen, with the ultrasound probe then scanning through this gel.
The gel helps improve contact between the probe and your skin. It involves scanning with the ultrasound probe lying in the vagina.
