Dating ultrasound heartbeat
Examples include the evaluation of fetal growth and the estimation of amniotic fluid volume.
A specialized or detailed exam is done when an anomaly is suspected based on your history or other prenatal exam results.
They also help to detect the foetal heartbeat and make it easier to determine the gestational age of the foetus.
If your health care provider doesn't suggest a fetal ultrasound but you'd like the reassurance an ultrasound can provide, share your wishes with your care provider so that you can work together to determine what's best for you and your baby.
It may simply be that the gestational age of the baby has been miscalculated.
To rule out this doubt, repeat the scan after a week to check for a heartbeat.
A transvaginal scan involves inserting the probe vaginally and for that, you need not have a full bladder.
However, if it is an abdominal ultrasound, a full bladder is necessary for a clear vision of the foetus.
However, the timing of this ultrasound might be altered for reasons such as obesity, which could limit visualization of the fetus.
