There are many possible causes for stomach pains like menstrual cramps in late pregnancy, and it is recommended to seek medical attention in case of unexplained cases. The first thing to consider when you have stomach pains in late pregnancy is whether you are going into labor, and if you see redness and regular contractions, you should go to the hospital in time. Secondly, pseudo contractions can also cause abdominal pain, but the frequency of pseudo contractions varies and their duration also varies. Furthermore, as the uterus increases in size during late pregnancy, the fetus also increases in size and its movement in the abdomen becomes more and more restricted, so when there is frequent fetal movement, there will also be stomach pain like menstrual cramps. The above three conditions are physiological and can be closely observed without treatment. However, if it is caused by pathological reasons, we should pay attention to it and seek medical attention as soon as possible. The common causes are: 1. Placental abruption. The abdominal pain is accompanied by vaginal bleeding, and the volume of blood is large and dark red in color. 2. Premature uterine rupture. If the body of the uterus or the lower part of the uterus ruptures, it is very dangerous and can endanger the life of the pregnant woman and the fetus. Be sure to seek medical attention in time and treat the symptoms.
