Twins usually show in the third to fourth month of pregnancy, but this is not absolute, and is related to individual circumstances, such as the thickness of the abdominal wall, the amount of amniotic fluid, and the development of the fetuses, etc. For example, slimmer women have less abdominal fat, and some women have thicker abdominal walls. For example, slimmer women with less abdominal fat usually show their pregnancy earlier, while some women with thicker abdominal walls may show their pregnancy 0.5-1 month later. Twin pregnancies are characterized by the presence of two fetuses in the uterine cavity, so the pregnant woman’s uterus will be more bulky, and the abdomen will show pregnancy earlier than single pregnancies. However, there is no need to pay too much attention to whether or not you are pregnant earlier, because clinically speaking, there is no more connection between early and late pregnancy and the development of the fetus. As long as the size of the fetus at the time of the ultrasound is in line with the gestational week, the fetus will grow and develop well even if it does not show. In addition, it should be noted that the risk of pregnant women pregnant with twins is greater than the risk of singletons, and there are more complications, such as hypertensive disorders in pregnancy is 3-4 times higher than the risk of singleton pregnancy, the incidence of anemia is 2.4 times higher than that of a singleton pregnancy, therefore, after the diagnosis of twin pregnancies, it is necessary to carry out routine examinations on time, and observe the development of the fetus at any time. Avoid excessive stress in life and ensure sufficient sleep. In the early stages of pregnancy, you can also take folic acid tablets as prescribed by the doctor, which can effectively prevent neural tube development malformation and anemia.
