Your ultrasound is always performed in the context of your clinical history and the results of previous ultrasounds and investigations.
Your baby will change dramatically in appearance during this early part of the pregnancy.
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 corpus luteum will gradually resolve (get smaller) as the pregnancy continues.
For many women, especially after 8 weeks gestation, sufficient information about the baby may be obtained with transabdominal ultrasound only.
Before 5 weeks gestation, the developing pregnancy is too small to detect on ultrasound.
The endometrium (the lining of the uterus where the pregnancy will grow) should appear thick and secretory.
Your doctor will discuss the reasons for such follow-up, if this is necessary.
We realise this is often an anxious time for parents, while they wait for the next ultrasound to check on their baby.
A full bladder moves bowel out from the pelvis into the abdomen, helping visualisation of the pregnancy, uterus and ovaries.
