Can the ultrasound show the result after 40 days?

When a woman becomes pregnant, her menstruation will stop, and she needs to go to the hospital for examination in time to understand the baby's health status. B-ultrasound is often chosen for examination. B-ultrasound examination should not be performed too early, otherwise not only will the baby's condition fail to be observed, but it will also affect the development of the fetus. So can the 40-day B-ultrasound show it? Let us find out.

First, can the ultrasound show it after 40 days? Actually, nothing can be seen after 40 days. Under normal circumstances, pregnant mothers should have an ultrasound examination in the early stages of pregnancy (around 12 weeks of pregnancy). Pregnant mothers should avoid having B-ultrasounds too early or too many times. Doing an ultrasound too early may cause the fragile, newly formed embryo to be shaken, which is not conducive to embryonic development. B-ultrasound in early pregnancy is to confirm whether the pregnancy is ongoing and how many days the pregnancy has lasted, to provide a reliable basis for determining the expected date of delivery, and to promptly detect any abnormalities in embryonic development.

Second, the main uses of abdominal B-ultrasound are as follows: routine gynecological examination. Observe the size of the ovaries, whether there are cysts, solid tumors, etc., and also observe whether there are uterine fibroids, adenomyosis, endometriosis, and endometrial polyps. Note: Ultrasound cannot diagnose atypical endometrial hyperplasia or endometrial cancer, and diagnostic curettage or endometrial biopsy is required for screening. Pregnancy check-up. Early pregnancy: can be used as a basis for diagnosis of early pregnancy. B-ultrasound examination is an important basis for confirming pregnancy. For those who are uncertain about the start date of their last menstrual period, B-ultrasound detection is the most accurate method. The size of the gestational sac can be calculated based on the results of the B-ultrasound examination, and the weeks of pregnancy and expected date of delivery can be estimated based on the length from the fetal head to the buttocks. In addition, the presence or absence of fetal heartbeat and yolk sac can be known, thereby promptly detecting abnormal development of the embryo.

Can it be revealed by ultrasound at 40 days? No, in the second trimester: ultrasound can be used to check for fetal anomalies. Color Doppler ultrasound can assist doctors in diagnosing congenital malformations of the fetus, including surface malformations and visceral malformations. For example, congenital heart disease, cleft lip and palate, hydrops fetus, polydactyly and external ear malformations can all be detected in newborns. At the same time, the exact position of the fetus in the uterus can be determined. Late pregnancy: During this period, ultrasound examination results are mainly used to assess how big and tall the fetus is, to observe the amount of amniotic fluid and the function of the placenta, and to see whether the fetus has the umbilical cord around its neck. If there is oligohydramnios, placental calcification, or the umbilical cord around the fetal neck, it is necessary to consider whether to continue the pregnancy based on clinical conditions.
