What is the normal head and hip size at 13 weeks of pregnancy?

After a woman becomes pregnant, regular checkups are necessary. Checkups can help uncover the condition of the pregnant woman and her fetus, and if any abnormalities are found, effective measures can be taken as soon as possible. Through B-ultrasound examination, you can observe a lot of data of the baby, such as body length, baby's head circumference and so on. So, what is the normal head and hip size at 13 weeks of pregnancy?

When a woman is 13 weeks pregnant, the fetus's brachiocephalic diameter is generally 6.5 cm. At this time, the fetus is about 10 cm long and weighs about 25 grams. Overall, the fetus at 13 weeks is still relatively small. But the baby's face has already shown its outline. In addition, the eyes are very prominent on the forehead, and the fetus's liver has just begun to secrete bile.

At 13 weeks of pregnancy, the pregnant woman's belly has already protruded slightly, and it can be seen that she is a pregnant woman. At this time, she should wear maternity clothes. Pregnant women can choose the color and style of maternity clothes according to their own preferences, but they must be easy to put on and take off and conducive to movement. The best fabric for maternity clothes is cotton or satin. The jeans worn by pregnant women should be looser, and overalls are the most suitable.

The 13th week of pregnancy is a critical stage for the growth and development of the fetus, so it is necessary to eliminate radiation sources. Therefore, pregnant women should avoid using computers, mobile phones and other items as much as possible, and they should also wear anti-radiation clothing for pregnant women. If you need to use your phone, it is best to use a headset for voice calls, and keep the phone farther away when you sleep at night.

The normal range of the head and arm diameter at 13 weeks of pregnancy is between 6.5 and 7.5 cm. There is a certain deviation in B-ultrasound, usually about one week. It is normal within this range. Regular prenatal check-ups are sufficient. As long as the growth and development detected by B-ultrasound is consistent with the gestational age, this problem is not a big deal. B-ultrasound is necessary at 13 weeks of pregnancy to check the nt value and minimally invasive DNA cleaning for abnormalities in the fetus. Daily nutrition is comprehensive and rich, sleep is sufficient, and the body's resistance is enhanced.
