Abdominal pain in the third trimester is a normal phenomenon and may also be a symptom of the disease.

Dysmenorrhea is mainly concentrated in the lower abdomen, often spasmodic pain. It is normal for the stomach to resemble dysmenorrhea in the third trimester, because with the increase of the fetus, the uterus will enlarge, and the pulling effect on the uterine ligament will be enhanced, which can lead to dysmenorrhea. During threatened labor, the fetus descends, and there will be fullness and oppression in the lower abdomen and waist. Before delivery, there may be false labor symptoms, manifested as contractions, but the duration is short, the intensity is weak, and the intermittent time is long and irregular, which often occurs at night and can also cause dysmenorrhea-like pain in the lower abdomen. But this kind of physiological lower abdominal pain, fetal movement and fetal heart rate are normal, and there will be no vaginal bleeding or vaginal running water.

Abdominal pain similar to dysmenorrhea in the third trimester of pregnancy may also be the manifestation of placental abruption, threatened premature delivery and threatened uterine rupture. For example, placental abruption may lead to bloating of the lower abdomen, which is as hard as a plate, and sometimes accompanied by vaginal bleeding. In severe cases, fetal movement can disappear and even go into shock.

Therefore, in the third trimester, the stomach looks like dysmenorrhea, so you should see a doctor in time and be diagnosed by a doctor.
