Why is the second child early?

More and more families are choosing to have a second child, mainly because of the continuous relaxation of national policies. However, many women will find obvious differences when they are pregnant with their first and second child. Normally, women who are pregnant with their second child will feel more relaxed and less stressed, mainly due to experience. However, some women find that they show signs of pregnancy earlier when they are pregnant with their second child. Why is that?

After giving birth to the first child, a woman's belly becomes looser, the skin on her belly is not as elastic as before, and the elastic fibers and collagen fibers of the skin are damaged to a certain extent, so her pregnancy is particularly noticeable. Secondly, when pregnant with the first child, the pregnant woman gains weight and has more abdominal fat, so the second child looks bigger. Because the abdominal skin is looser, fetal movements with the second pregnancy will appear slightly earlier than with the first pregnancy. Pregnant women should pay attention to rest and strengthen nutrition during pregnancy.

If the second baby is revealed early, is it a boy or a girl?

Generally, the second child will have more obvious symptoms. The pregnancy will be apparent earlier, the fetal movement will also be earlier, the birth will be much faster than the first child, and the contractions will be shorter. However, you have to see if the weight gain is normal. You can't gain weight too quickly.

We can only know that the fetus develops earlier, which has nothing to do with the sex of the fetus. It is recommended that you choose to do a maternal blood test. After the blood sample of the pregnant woman is drawn, it is first subjected to two high-speed centrifugation processes, and the upper clear liquid is transferred into a new sterile tube and frozen for later use. Then use reagents to extract the DNA in the supernatant, stain it, and observe it under ultraviolet light. If you see a SRY band it means it's a boy, if you don't see it it means it's a girl. The inspection reliability is approximately 99%, and the inspection results will be available in approximately 3-5 days.

Ultrasound scan to determine the gender of the baby

1. Ultrasound is a type of sound wave. Reports so far have shown that it has no adverse effects on the fetus, so it is widely used in obstetrics and gynecology.

2. When the ultrasound probe slides over the expectant mother's gel-coated belly, the baby's ultrasound image will be displayed on the ultrasound doctor's screen. Generally speaking, by the 18th week of pregnancy, if it is a girl, the vagina, uterus, and fallopian tubes are all in place; if it is a boy, the external genitalia are also clearly visible. In the B-ultrasound image, the male reproductive organ is shaped like a pot handle, while the female reproductive organ is shaped like petals. The basis for doctors to determine the sex of the fetus is very simple - if the handle is present, it is a boy; but if the handle cannot be seen clearly, it is difficult to say.

3. Why can't we see clearly and feel uncertain? This is because sometimes the boy's "that thing" will be blocked by other body structures due to the special position in the womb. Even experienced doctors can only let it go and it is difficult to make a judgment at the moment. The accuracy of B-ultrasound in determining whether a baby is a boy can reach over 95%, while the accuracy of B-ultrasound in determining whether a baby is a girl is only around 85%. The detection accuracy is higher after the fetus is 4 months old.
