How long does it take to do a vaginal ultrasound during pregnancy?

Many people think that it is unsafe to do a vaginal ultrasound after pregnancy, so even if the doctor recommends it, they still dare not do it. In fact, vaginal ultrasound can be done during pregnancy, but it is best to avoid the two more dangerous stages of early and late pregnancy. The best time for vaginal ultrasound is in the middle of pregnancy. It will not cause miscarriage, and because vaginal ultrasound is closer to the uterus, the examination will be clearer.

Pregnant women can have a transvaginal ultrasound.

Because the vagina is close to the uterus and ovaries, and the probe is powerful, the image obtained is clear and the resolution is high. Small lesions can be clearly observed, and the blood flow of the uterus and ovaries can be detected. Therefore, the examination results are more accurate. It is particularly suitable for examining small lesions such as the endometrium, follicular development, and observing early ectopic pregnancy. The images obtained by vaginal B-ultrasound are clearer and have higher resolution, and the results of early pregnancy tests are more accurate.

In clinical practice, doctors sometimes combine abdominal B-ultrasound and vaginal B-ultrasound examinations to complement each other and achieve the best diagnostic effect.

However, although vaginal B-ultrasound is simple, it is not suitable for everyone. Unmarried women, people with vaginal bleeding, bleeding in mid-to-late pregnancy or during pregnancy, or people with large pelvic masses should not undergo transvaginal ultrasound.

Precautions for pregnant women to do vaginal ultrasound

1. Check the time

It is generally recommended to perform B-ultrasound vaginal examination three to seven days after the menstrual period ends, which can effectively avoid gynecological infections. If you want to monitor the follicles through B-ultrasound vaginal examination, it is recommended to start B-ultrasound vaginal examination on the 3rd day after the menstruation ends, and perform follicle monitoring every two days.

2. Applicable people

B-ultrasound vaginal examination is not suitable for every woman. For example, those who have no sex life are not suitable for B-ultrasound vaginal examination, otherwise it will cause damage to the hymen. For example, it is not recommended to use B-ultrasound vaginal examination for people with vaginal bleeding, large pelvic masses, pregnant women, etc. Except for the above-mentioned people, basically everyone is suitable for B-ultrasound vaginal examination.

3. Preparation

Before doing a B-ultrasound vaginal examination, you need to do the following preparations: First, refrain from sexual intercourse the day before the examination to avoid affecting the examination results. Second, pay attention to the cleanliness of the vulva, otherwise it is easy to bring dirt into the vagina, leading to nosocomial infection. Third, you need to empty your urine when doing a B-ultrasound vaginal examination, otherwise it will affect the examination results. So, you should urinate before the examination.
