hCG is a hormone produced early in pregnancy. It helps to nourish and protect the embryo. By checking hCG levels, doctors can assess the health of a pregnancy. Many women want to know what high hCG levels mean and in which cases hCG may become higher than normal.

Ultrasound is one of the essential clinical techniques during pregnancy because it can assess the development of the fetus inside the mother's womb. Therefore, it is necessary to understand information such as whether you can eat before an ultrasound, whether you need to fast for the first ultrasound, etc., to prepare for the best ultrasound procedure.
