A woman’s pregnancy is counted as one month for every 4 weeks, so the 7th trimester is usually about 28 weeks of pregnancy. The clinical calculation of the gestational week requires first specifying the date of the first day of the last menstrual period and counting from the first day of the last menstrual period, every 7 days is one gestational week, while the 7th month of pregnancy can also be calculated in this way. Pregnant women in the 7th month of pregnancy can start to record fetal movements to prepare for the late stage of pregnancy. At this time, the mother usually feels more fatigued and will have uncomfortable symptoms such as swollen feet, swollen legs and varicose veins, so she needs to exercise in moderation and should not stand for a long time. In addition, pregnant women need to pay attention to the prevention of diabetes during pregnancy, gestational hypertension syndrome and preterm delivery during this period. In addition, since pregnant women may suffer from calcium deficiency and convulsions in the 7th month of pregnancy, they need to supplement nutritious foods with high calcium content, such as milk, eggs, tofu, etc.
