The medical name for an aunt is menstruation, and a stomach ache a week before menstruation does not indicate a sign of pregnancy, but may also be caused by premenstrual abdominal pain. Generally speaking, it is possible for women to experience stomach pain in the early stages of pregnancy, but some women also experience stomach pain before their period, such as the more common clinical menstrual cramps, so stomach pain a week before menstruation is not a basis for determining whether a woman is pregnant or not as a sign of pregnancy. Therefore, if the patient has recently had sex, it is recommended that the patient go to the hospital for relevant laboratory tests to determine whether pregnancy. If it is not caused by pregnancy, it is recommended that patients pay attention to keep warm in their daily life and avoid eating spicy and stimulating food, so as not to aggravate the symptoms of stomach pain. To summarize, stomach pain one week before menstruation can not be used as a basis for detecting pregnancy, it is recommended that patients go to the hospital for relevant tests to confirm.
