Pregnancy, also known as pregnancy, refers to the reproduction and growth process of embryos or fetuses in mammalian females. The whole process of human pregnancy can be divided into three stages: early pregnancy, second pregnancy and third pregnancy. Good health care during pregnancy can improve the physical condition during pregnancy, including taking more folic acid, avoiding drugs and alcohol, and exercising and checking regularly. After the second trimester of pregnancy, the uterus is obviously enlarged, and you can touch the carcass, feel fetal movement and hear fetal heart sounds. It is easy to be diagnosed. Uterine enlargement With the progress of pregnancy, the uterus gradually increases. When examining the abdomen, it is helpful to judge the gestational age by measuring the height of the fundus by hand and the length of the uterus above the pubic bone with a ruler. The height of uterine fundus varies with the distance between umbilical cord and pubic bone, fetal development, amniotic fluid volume, singleton or multiple births and other factors. Fetal movement The activity that the fetus impacts the uterine wall in the uterus is called fetal movement. Fetal movement is a sign of good fetal condition. Pregnant women began to consciously move their fetuses at 18-20 weeks of pregnancy. The more weeks of pregnancy, the more active fetal movement, but it gradually decreases at the end of pregnancy. Fetal movement is about 3-5 times per hour.
