An ultrasound scan sends high-frequency soundwaves through your uterus (womb). These bounce off your baby and the echoes are turned into an image on a screen that shows your baby\'s position and movements.
Treasured though this image will be, remember that the purpose of the scan is not to provide the first photo for your baby album. It is to check that your baby is developing normally.
HOW SAFE IS SCANNING IN PREGNANCY?
IT IS CONSIDERED VERY safe .no radiation hazards for the growing fetus as it is kept to the very minimal exposure.
Ultrasound has been used in pregnancy for nearly 30 years and there are no known side-effects. No link has been found between scans and a baby\'s birthweight, childhood cancer, sight and hearing problems, or dyslexia.
