The best time for the first ultrasound during pregnancy

Pregnant women must have regular B-ultrasound during pregnancy, and the time must be well managed. Generally, the first B-ultrasound is performed within March, preferably in the 8th week. It must be done during the non-menstrual period, otherwise it will have effects. The following will explain to you the best time for the first B-ultrasound.

1. The best time for the first ultrasound during pregnancy

In the early stages of pregnancy, the first ultrasound examination should be performed within three months, and the best time to check is the eighth week, which is about one and a half months after the menstrual period ends. The menopause time is calculated from the first day of menstruation. This type of optimization algorithm is applicable to people with regular menstruation and a physiological cycle of 28-30 days.

2. Reasons for doing B-ultrasound in early pregnancy

1. B-ultrasound examination is a necessary examination for pregnant women during pregnancy. It is a kinetic energy examination and does not produce X-ray electromagnetic radiation. As far as the wave volume and exposure time used in clinical examinations of pregnant women are concerned, its safety can be guaranteed.

2. The key to the first B-ultrasound is to determine the number of weeks of pregnancy, the location of pregnancy, and the total number of gestational sacs (single or multiple births). If it is found to be an ectopic pregnancy, it needs to be handled properly. It is best to defuse the "time bomb" before the ectopic pregnancy breaks out and bleeds to avoid serious consequences.

3. Among the 12 prenatal checkups required by the current standard maternity medical insurance, the frequency of B-ultrasound examinations is 5 times, which is the uniformly required frequency of B-ultrasound examinations during pregnancy, including the early stages of pregnancy.

4. It is very important to choose the right time to carry out ultrasound examination, because the screening of some diseases has strict time limits. In addition, if there is vaginal bleeding or abdominal pain in early pregnancy, a follow-up ultrasound examination is required at intervals of 7-10 days to understand the condition of the fetus, especially in patients whose embryos have stopped developing in the past.
