In the second month of pregnancy, if there is abdominal pain, we should consider the following reasons: First, physiological abdominal pain is due to the gradual enlargement of the abdomen and uterus after pregnancy, which has a certain impact on the surrounding organs in the abdomen. And after the uterus becomes bigger, the ligaments around the uterus have loosened and become taut, which can lead to a tingling sensation in the stomach. This is a physiological condition and does not require special treatment. Secondly, pathological phenomena include gynecological inflammation and intestinal diseases; gynecological inflammation includes cervicitis, adnexitis, pelvic inflammatory disease, etc.; intestinal diseases include enteritis, intestinal spasm, intestinal obstruction and other conditions. In addition, the occurrence of bilateral ureteral stones can cause abdominal pain in early pregnancy, and pathological abdominal pain requires pregnant women to go to the hospital for examination and diagnosis in a timely manner.
