Modern medical methods are really advanced. Nowadays, there are various medical devices to detect whether a child has any abnormalities in the belly. If the pregnancy time is unknown, there is also a negative ultrasound test to determine how many days the child has been in the belly. There are methods to quickly detect pregnancy if it is uncertain. So, is the pregnancy duration of vaginal ultrasound accurate?
The pregnancy duration of vaginal ultrasound may not be accurate, and its examination results may have errors. The pregnancy duration is calculated from the first day of the last menstrual period, rather than from the time of fertilization, which is more accurate for pregnant women who are already pregnant and have intrauterine pregnancy. Pay attention to rest, eat more fruits and vegetables, avoid sexual intercourse, and have regular pregnancy checkups.
What should I pay attention to after pregnancy?
1. Regularly undergo prenatal check ups. The time for a baby to be conceived in the mother's womb is usually around 42 weeks. During these 42 weeks, depending on the baby's developmental status, it can be divided into three stages: early pregnancy, mid pregnancy, and late pregnancy. The content to be inspected during each stage is also different.
2. Pay attention to staying away from radiation sources in daily life. Reduce the use of mobile phones and computers, and strictly control the time spent watching TV within one hour. In addition, kitchen appliances and the like should also be avoided. Never use a microwave oven, as the radiation is at its maximum at the moment of startup. If necessary, you can wear medical radiation protective clothing. The purchase of radiation protection clothing must go to a professional and legitimate store.
