As is well known, after pregnancy, women need to go to the hospital for B-ultrasound examination to determine the specific development of the fetus in the abdomen. But most women do not have professional medical knowledge, and the ultrasound examination form given by doctors cannot tell the reason, such as how many weeks does the ultrasound show as 6 × 5? You know what?
The ultrasound shows that 6 × 5 is around 5 weeks. Go to the hospital for a B-ultrasound examination. The B-ultrasound examination form will show the fetal sac, fetal head, fetal movement, placenta, amniotic fluid, spine, and other conditions. According to the specific condition of the gestational sac, the number of days of pregnancy can be calculated. The B-ultrasound data sheet is generally represented by GS. Generally speaking, when a woman stops menstruating for about 35 days, the gestational sac can be seen through B-ultrasound.
So how to determine the gestational age through the gestational sac and is there any method? The answer is yes, there is a calculation formula here, the size of the gestational sac (length+width+height)/3+30, and the result is the number of days. For example, if the size of the gestational sac is 6 × 5 × 5, the calculation method is (6+5+5)/3+30=35 days, which is 5 weeks.
Generally speaking, from pregnancy to pregnancy, it is necessary to undergo approximately 4 B-ultrasound examinations. The first B-ultrasound examination should be performed at 8-10 weeks, the second B-ultrasound examination can be performed at 14 weeks, the third B-ultrasound examination should be performed at 24-25 weeks, and the fourth B-ultrasound examination should be performed at 30-32 weeks. Pregnancy is a big deal, and expectant mothers can arrange a time to go to the hospital for a B-ultrasound examination based on their actual situation and the doctor's advice.
