Vague abdominal pain in early pregnancy, abdominal pain during pregnancy is a common problem encountered by pregnant women. The abdominal pain can be physiological abdominal pain, or it can be a warning of the occurrence of certain diseases in the body, and pregnant women should be cautious about it. Some physiological abdominal pains, such as stomach pain in early pregnancy, may be accompanied by vomiting and other early pregnancy reactions, which are caused by increased secretion of stomach acid in early pregnancy. In more serious cases, pathological abdominal pain should be identified. If abdominal pain occurs in early pregnancy, especially in the lower abdomen, the possibility of pre-eclampsia should be considered. Premature miscarriage is characterized by paroxysmal pain in the lower abdomen, which is regular and may be accompanied by pain in the lower back and pelvis, more obviously by bleeding in the vagina and a more pronounced feeling of abdominal distension. If there is unilateral lower abdominal pain with vaginal bleeding or fainting, the possibility of ectopic pregnancy or ectopic pregnancy cannot be ruled out. The abdominal pain should not be taken lightly and should be examined by a hospital in time to clarify the cause before treatment.
