Ectopic pregnancy is an abnormal pregnancy state where the fertilized egg implants outside the uterine cavity. As the pregnancy sac grows, there is a possibility of rupture and bleeding at the implantation site, which can lead to abdominal pain. In the early stages of an ectopic pregnancy, women generally do not exhibit any specific symptoms and are unaware of the condition. Symptoms are only felt when rupture occurs, causing pain in the lower abdomen. If rupture occurs, the pain often feels like tearing in the lower abdomen and is frequently accompanied by nausea and vomiting. It is recommended to promptly visit a hospital for an ultrasound and actively pursue surgical treatment.
