Tummy pain during pregnancy is a normal physiological reaction that occurs in early pregnancy, as the uterus enlarges and stimulates the bones, and the pregnant woman feels a vague pulling pain in the abdomen. However, it is worth noting that if the stomach pain persists with symptoms of bleeding, you should be admitted to the hospital immediately for examination. This pathological stomach pain may indicate signs of miscarriage, or the occurrence of ectopic pregnancy, etc. Therefore when the stomach pain in early pregnancy occurs, we have to learn to distinguish whether it is a physiological abdominal pain or a pathological one. The specific causes of stomach pains during pregnancy are the enlargement of the uterus and irritation of the bones. When you are pregnant you will feel that your stomach is getting bigger day by day and your skin has a tight feeling. If you are very athletic, you will feel a vague pulling pain in your abdomen after a hike, or after playing ping pong, similar to the usual stomach pain. Some mothers-to-be may experience dull rib pain due to the enlargement of the uterus, which constantly stimulates the lower edge of the rib cage, or pain due to the separation of the pubic symphysis filling, resulting in restricted movement. However, these conditions are normal physiological reactions to pregnancy and do not require treatment. The pain can be relieved by sleeping on the left side. The mother-to-be does not need to worry and can be relieved by more bed rest. For pathological reasons caused by ectopic pregnancy, uterine adnexa and other diseases, the stomach pain in early pregnancy is more obvious and unbearable, and the pregnant mother should go for blood hcg examination to exclude pre-miscarriage or ectopic pregnancy. Further comprehensive physical examination will then be done to rule out other uterine adnexal diseases.
