Pregnancy dating scan accuracy english dating bg
The corpus luteum will gradually resolve (get smaller) as the pregnancy continues.
At 5-6 weeks gestation, a small gestation (pregnancy) sac is seen within the uterus.
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.
Some women need to return for another ultrasound scan a few weeks later to assess the progress of the pregnancy, or they may require another blood test (serial serum Bh CG).
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).
