How many days in early pregnancy should I do B-ultrasound?

Nowadays, medical technology is becoming more and more advanced, and many people are paying attention to their diet, health and lifestyle arrangements every day. But don’t forget that if you are preparing for pregnancy, you should regularly check whether you are pregnant. You can check with early pregnancy test strips. Once the pregnancy is detected, you should go to the hospital for B-ultrasound. Generally, when is the best time to do B-ultrasound in the early pregnancy?

How long after pregnancy is it appropriate to do B-ultrasound

1. Is Ultrasound Safe?

1. Ultrasound has certain biological effects. Although there is currently insufficient evidence to prove that diagnostic ultrasound is harmful to the fetus, it still needs to be used with caution on early embryos.

2. In 2002, ISUOG reiterated: Do not perform the examination for too long, and limit ultrasound examinations to medical indications and not for recreational purposes.

3. Therefore, it is recommended to avoid multiple ultrasound examinations during the first three months of pregnancy.

What can early pregnancy ultrasound detect?

1. Determine whether you are pregnant;

2. Pregnancy location, size, shape, presence of gestational sac, and fetal heart rate;

3. Determine the number of gestational sacs and embryos, and the chorionicity of twins;

4. Observe the embryo and determine whether the embryo has stopped developing;

5. Whether there is ectopic pregnancy (ectopic pregnancy). It is well known that rupture of ectopic pregnancy will cause massive intra-abdominal bleeding, which can be life-threatening in severe cases!

6. Whether there are any gynecological complications (such as uterine malformation, myoma, adnexal cyst).

3. Vaginal Ultrasound

The gestational sac can be found about 30 days after amenorrhea (equivalent to 16 days after ovulation or 10 days after implantation), and abdominal ultrasound can diagnose early pregnancy 35 days after amenorrhea (21 days after ovulation); at this time, a round or oval gestational sac can be seen in the uterine cavity; at 6 weeks of pregnancy, the embryo and primitive heart tube pulsation can be seen.

4. Can ultrasound detect any abnormalities in the baby?

Since ultrasound diagnosis is based on morphology, ultrasound cannot diagnose when there is little or no morphological change (such as eye and ear abnormalities, limb joint curvature, angle abnormalities, and finger and toe abnormalities, etc.)

Therefore, even if the ultrasound examination does not find any abnormalities, it cannot 100% rule out the possibility that there are problems with the fetus.

Through the introduction in this article, we can know that pregnant women can have their first B-ultrasound examination at 5-6 weeks after menstruation, or at 10 weeks of pregnancy. In fact, the later the first ultrasound is done by a pregnant woman, the better. However, if necessary, you must actively do the ultrasound and cannot postpone it at will.
