How to calculate the pregnancy formula for men and women?
B-ultrasound data of 1 and 7W 1D: gestational sac 2.95438+0.9, boy. 2.9W4D B-ultrasound data information: The uterine cavity is 46.630.2mm gestational sac, and the twin babies are girls. 3, 60 days of B-ultrasound data information: gestational sac 3.6 1.6mm, a boy. 4.5W6D B-ultrasound data: gestational sac is 25mm 1 1mm, and it is a boy. 6, 46 days of B-ultrasound information: gestational sac 2b25b250 periodontal 17mm periodontal 17mm, female baby. 7.7w 1D ultrasound results: gestational sac 322b25b250, female baby. B-ultrasound data of 8-7 weeks or more: The gestational sac with a uterine cavity of 3.82.3cm is a boy. More than 9 or 8 weeks old, it was a B-ultrasound, gestational sac 19mm 1b25b250, and it was a boy. 10, at 8 weeks, it was 4 128mm, and it was also a female baby. 1 1 and 62 days of B-ultrasound data information: The uterine cavity showed that gestational sac 2.6 1.8 was a boy. 12,50-day B-ultrasound data: gestational sac 35 mm, 27 mm is a female baby. 13, gestational sac: 35mm, periodontal 34mm, periodontal 28mm. It's a female baby. 14, gestational sac: 18mm periodontal 16mm periodontal 8mm, female baby. 15, gestational sac length 442b25b250, it's a boy.
In addition to the above calculation formula, there is this popular method:
1. The gestational sac is round, so the probability of giving birth to a girl is very high. If the abdomen is green beans or long strips, the chances of having a boy are very high.
2. Look at the length of the gestational sac. If the relationship between length and width is twice, then the probability of a boy is very high. If they are almost the same length, there is a great possibility of having a girl.
Suggestions on supplementing trace elements before pregnancy
The first month of pregnancy, that is, the third to eighth week of the whole process of embryonic development, is a critical period for the important human internal organs of the fetus (such as the heart, central nervous system and limbs) to develop sores. If there are not enough vitamins and minerals at this time, it will not only easily lead to birth defects of the fetus, but also affect pregnant women to a certain extent.
Therefore, it is particularly important to make a good pregnancy plan and supplement pregnant women's vitamins as soon as possible. During pregnancy, women's demand for trace elements, such as vitamins, continues to rise compared with pregnancy, so it is impossible to obtain multi-directional and balanced supplements on the basis of all normal dietary supplements. Generally, we can't consider the ingredients contained in various nutrients for pregnant women, which will easily lead to the lack of various trace elements and minerals including folic acid, and the lack of vitamins and minerals such as folic acid will easily lead to various birth defects such as neural tube defects in newborns.
