The vague pain in the stomach just after pregnancy can be seen in the physiological pain caused by pregnancy, but also in abnormal conditions, and the abdominal pain caused by different reasons is handled differently. 1, if it is clear that the early intrauterine pregnancy, the vague stomach pain is mainly considered to be physiological abdominal pain caused by pregnancy, which is a normal physiological phenomenon, because early embryonic implantation, uterine ligament pulling, hormonal level changes in the body leading to accelerated metabolism in the body may induce abdominal pain. The pain is often short-lived, episodic on both sides of the lower abdomen, aggravated by exertion and relieved by lying down and resting. At this time, we should pay attention to maintenance, prevent cold, and eat less spicy and sour food, which can effectively relieve the pain. If the hidden pain is long, gradually aggravated, or accompanied by a little vaginal bleeding, do not exclude the possibility of pre-eclampsia, you need to immediately go to the hospital to recheck the blood HCG and do ultrasound to clarify the diagnosis. 2.If intrauterine pregnancy is not clearly identified and hidden pain in the stomach occurs, it is necessary to be alert to the possibility of ectopic pregnancy, such as tubal pregnancy. The pain caused by ectopic pregnancy is often manifested as prolonged, one-sided lower abdominal pain, which is gradually stronger. At this time, it is necessary to seek medical attention immediately, because ectopic pregnancy progresses rapidly and can cause syncope and shock or even endanger life in case of rupture. If a pregnant woman has not been to the hospital, but has a positive urine test paper test at home, it does not exclude the possibility of false pregnancy and the possibility of gastroenteritis, pelvic inflammatory disease, appendicitis, etc. The cause needs to be clarified by the doctor in time. To sum up, if you experience vague stomach pain in early pregnancy, you should go to the hospital for safety reasons to clarify the cause, rather than carrying it at home to avoid ectopic pregnancy rupture and hemorrhage, which may endanger your life.
