Ectopic pregnancy can be detected in the fifth week of pregnancy with regular menstruation. Pregnancy can be confirmed by a urine test or a blood HCG level about half a month after menstruation. In women with intrauterine pregnancy, a gestational sac can be detected in the uterus and the heartbeat of the fetus can be detected. If you eat and drink normally during pregnancy and your body reacts normally, you can not worry. If there is abdominal pain, abnormal vaginal bleeding and no gestational sac can be detected in the uterus during ultrasound examination, there may be a risk of ectopic pregnancy. It is important to confirm the diagnosis in combination with other relevant tests. If the diagnosis is ectopic pregnancy, it should be treated promptly and follow the guidance of a professional doctor. Untreated ectopic pregnancy can lead to the risk of rupture of the ectopic pregnancy, which can adversely affect the woman’s body.
