Why is it easy to abort?

A vaginal sonography is not inherently miscarriage prone.

First, it is a safe and reliable ultrasound procedure. During vaginal sonography, the ultrasound probe is gently placed in the vagina and does not cause direct mechanical stimulation or damage to the uterus and gestational sac. Second, for pregnant women in early pregnancy, the doctor will carefully select the examination method according to the specific circumstances. If the pregnant woman has abnormal conditions such as vaginal bleeding, abdominal pain or signs of threatened abortion, transabdominal ultrasound may be preferred. However, a vaginal ultrasound can be performed if the circumstances warrant, and it does not increase the risk of miscarriage due to the examination itself.

Pregnant women should trust their doctor's professional judgment and advice without excessive worry or fear about the vaginal ultrasound examination.
