Under normal circumstances, the third trimester fetus is in the uterus. When a pregnant woman is lying down, the lump that can be touched about 2-3 fingers below the navel is the location of the fetus, and a thinner pregnant woman can be touched above the pubic symphysis. After a woman is pregnant, the embryo develops in the uterus, under normal circumstances, the uterus is located in the pelvic cavity, later as the embryo develops, the uterus gradually increases, the third trimester fetus is equivalent to about 12 weeks of pregnancy, the fetal development and differentiation has taken on a human shape, but the size of the fetus is small, the uterus does not increase significantly, the uterus can protrude into the pelvic cavity after the third trimester, and gradually increases with the increase in pregnancy. If you want to know more about the exact position of the fetus, it is recommended that you have an ultrasound examination to obtain the exact position of the fetus. If the ultrasound result shows that the fetal position is not correct, it is normal and does not need to be corrected artificially, usually the fetal position can be fixed after 28 weeks of pregnancy, so pay attention to the growth and development of the fetus and perform pregnancy checkups regularly. In the third trimester, the pregnant woman’s belly is growing and her weight is increasing, her breasts will continue to get bigger, so she can choose loose underwear and outerwear. If there is pain or abnormal smell, it is recommended to seek medical attention. Pregnant women may also have nausea, vomiting and dizziness at this time, so they can choose foods that are easy to digest and absorb, such as millet porridge, steamed fish and sliced bread.
