Occurrence of vague abdominal pain in early pregnancy usually disappears basically on its own after 3-5 days or at most 10 days. Usually, due to the change of estrogen and progesterone in the body in early pregnancy, it is normal to have a mild localized vague pain with very low frequency and very mild abdominal pain every day. If the abdominal pain is frequent and intense, it is necessary to seek medical attention in time to exclude the hidden abdominal pain caused by some other abnormal conditions, such as proctitis, appendicitis, etc., which may also be caused by early pregnancy reaction.
