Vaginal ultrasound, also known as transvaginal ultrasound, refers to the examination method of placing an ultrasound probe into the vagina or rectum. Unmarried women without sexual activity are not recommended to undergo vaginal ultrasound to avoid damaging the hymen. Women who are menstruating should also avoid undergoing vaginal ultrasound to prevent infection. So, can a negative ultrasound be performed if there are signs of threatened miscarriage?
Whether or not to perform a vaginal ultrasound with signs of threatened miscarriage depends on the situation. If it has been determined to be threatened miscarriage, vaginal ultrasound cannot be performed. Otherwise, vaginal ultrasound examination can be performed. Because transvaginal ultrasound is a method of inserting an ultrasound probe into the vagina for examination, abdominal pain and vaginal bleeding may occur during threatened miscarriage.
Performing a vaginal ultrasound examination can easily lead to infection on one hand, and on the other hand, it can stimulate the cervix and worsen uterine contractions. In addition, many pregnant women may feel itching and discomfort in the vagina after undergoing vaginal ultrasound examination, so it is recommended not to undergo vaginal ultrasound examination after pregnancy. In order to avoid causing harm or adverse effects to pregnant women, exposure to negative ultrasound examination should be avoided. A better examination method after threatened miscarriage is abdominal ultrasound examination, which can also understand the position and development of the embryo, as well as whether there is internal bleeding in the uterine cavity.
Abdominal ultrasound examination is a non radiative ultrasound examination that uses corresponding sound waves to perform corresponding images, and will not cause harm to the fetus or pregnant woman. Therefore, pregnant women do not need to worry when undergoing ultrasound examinations.
