A twin pregnancy is considered full term at 37 weeks of gestation, and like a singleton pregnancy, it is also defined as 37 weeks of gestation, and after 37 weeks of gestation is called full term. Twin pregnancies are a type of high-risk pregnancy that can lead to complications such as preterm labor. Preterm labor is caused by premature rupture of the membranes due to excessive pressure in the uterine cavity, which can lead to preterm labor. It can also be caused by the significant enlargement of the pregnant woman’s uterus, which leads to excessive expansion of the uterus and contractions or even weak contractions, which can further lead to preterm labor. In addition, pregnant women with twin pregnancies are prone to complications such as hypertension or anemia during pregnancy, which can be a cause of preterm labor. First of all, women should not collide with their abdomen during twin pregnancy and should not go to crowded places after pregnancy so as to reduce crowding or collision. Don’t take heavy things or things from high places to avoid stimulating the abdomen. Next, practice good bowel habits to avoid stimulating the uterus to cause contractions. In case of abdominal pain, vaginal bleeding or pink discharge, seek medical attention promptly so that the doctor can determine whether there is a preterm miscarriage or preterm labor.
