The 28th week of pregnancy is the 7th month of pregnancy, or more precisely, the end of the 7th month of pregnancy. The medical determination of pregnancy is not based on the day of union of sperm and egg as the first day, because the day of ovulation of a woman may be early or delayed. For the convenience of calculation, the first day of the last menstrual period is counted as the beginning of pregnancy and extrapolated backwards to 280 days of pregnancy as the expected date of delivery. At the same time, every 7 days is a gestational week and 4 gestational weeks are a gestational month, which means that a gestational month is actually 28 days and the whole pregnancy has 10 gestational months or 40 gestational weeks, or 280 days. For example, if the first day of the last menstrual period is on April 1, the due date is January 8, and so on. In the 7th month of pregnancy, you are in the late stage of pregnancy, fetal movement will be more frequent, it is recommended to do a maternity check every half month, and every 1 week from 36 weeks. In addition, pay attention to proper exercise to strengthen the body’s resistance to reduce the occurrence of colds, diarrhea and other diseases. If the fetal movement is less than 3 times per hour or more than 10 times per hour, you should be alert to the possibility of fetal hypoxia in utero. Pay attention to reasonable rest and ensure sufficient sleep. Take a reasonable diet and pay attention to strengthen nutrition. Avoid sitting or standing for a long time, which is not good for the development of the fetus.
