The symptom of vague pain in the stomach just after pregnancy may be a normal physiological manifestation of early pregnancy, or it may be caused by abnormal factors such as preterm miscarriage and ectopic pregnancy. I. Normal physiological phenomenon: The fertilized egg will gradually develop after it is laid in the uterus, and the uterus will gradually become engorged and enlarged with the growth of the embryo, which can cause occasional vague pain in the stomach of some pregnant women. Generally, it can be relieved by rest, but it is necessary to pay attention to prohibit strenuous exercise and sexual life. Abnormal factors: 1. Premature miscarriage: vaginal bleeding may occur, accompanied by continuous vague contraction-like pain in the lower abdomen or low back pain. It is necessary to seek medical attention, take strict bed rest, avoid tension, avoid straining, and prohibit sexual intercourse in the early stage. 2. ectopic pregnancy: before rupture, it may also be manifested as vague pain in the stomach, and after rupture, it may be manifested as sudden, persistent stabbing or tearing pain, and vaginal bleeding, accompanied by nausea and defecation. Early ectopic pregnancy can be treated with medication or, if necessary, surgery. If you have pain in your stomach in early pregnancy, you can go to a regular hospital for progesterone, HCG and ultrasound tests to determine the cause of the pain and take treatment as soon as possible to avoid adverse consequences.
