Can I go for the prenatal check-up a few days in advance?

Prenatal check-ups can be done one or two days in advance, but prenatal check-up measures need to be taken during the check-up, and pregnant women must go for the check-up according to the doctor's advice. The purpose of prenatal check-up is to check whether the fetus is developing normally. This is our main method to prevent fetal malformations and infectious diseases. Prenatal check-up can also tell us what the pregnant woman’s physical condition is like, which can bring great convenience to the pregnant woman’s delivery.

Can I go for the prenatal check-up one day in advance?

It is okay to go for a prenatal check-up one day in advance. There is nothing wrong with it. You can just go for a direct check-up. It will not have any impact. Now we mainly check the development of the fetus, as well as the amniotic fluid, placenta, fetal position and so on.

Ultrasound examination can only see the gestational sac after 5 weeks of pregnancy, and the detection rate of the gestational sac reaches 100% at 6 weeks of pregnancy. The embryo can be seen at 6-7 weeks of pregnancy. At 49 days of pregnancy, when the diameter of the embryo is 2mm, the primitive heart tube beating can be seen. At 8 weeks of pregnancy, the human shape begins to take shape.

All organs are formed at the 14th week, hair begins to appear at the 15th week, and the uterus is about 16CM at the 16th week.

At the end of the 17th week, the baby's movements are restricted and fetal movements occur. The second scan (to determine gender) is done at the end of week 21. The gender will be known at the end of the 22nd week.

If you do an ultrasound too early, it will not be easy to see the shadow of the gestational sac because it is too small. Not every doctor can make an accurate diagnosis, and it depends on the experience of the person doing the imaging, and the more they do, the better. Ideally, it will be easily visible at 8-10 weeks of pregnancy. And if you do B-ultrasound too early, it will theoretically shock the fragile, newly formed embryo, which is not conducive to embryonic development. It is best to avoid doing B-ultrasound too early or doing it multiple times.

The height of the pregnant mother's uterus and abdominal circumference are closely related to the size of the fetus. During the early and mid-pregnancy, there is a certain standard for monthly growth. It is necessary to know the length of each gestational week. In the later stages, by measuring the uterine height and abdominal circumference, the weight of the fetus can also be estimated. Therefore, during every prenatal check-up, the uterine height and abdominal circumference should be measured to estimate the intrauterine development of the fetus. At the same time, the uterine height pregnancy chart can be used to understand the intrauterine development of the fetus and whether it is developmentally delayed or macrosomia.

The enlargement of the uterus during pregnancy is regular, manifested as an increase in the base and abdominal circumference. Generally, it is measured once every 4 weeks starting from the 20th week of pregnancy, once every 2 weeks from the 28th to 35th week of pregnancy, and once a week after the 36th week of pregnancy.
