What are the symptoms of ectopic pregnancy?

Patient's question:

This morning, I took a "human chorionic gonadotropin" test, and the result was 559.56 (units: mIU/ml). Last night, I had mild pain in my lower left abdomen, and the pain worsened when I pressed hard with my hand! Today, I haven’t had any pain symptoms all day. A few days ago, I also had mild abdominal pain.
The pants I’m wearing are a bit tight, and my feet feel a bit cold. Could this be causing the abdominal pain?
Is it possible that this could be an ectopic pregnancy?
Yesterday, I had an ultrasound, but it didn’t show the fertilized egg implanting in the uterine cavity. What’s going on?

Doctor's answer:

Main symptoms of ectopic pregnancy
1. Menstrual delay, ranging from several to dozens of days, often occurring without being noticed.
2. Abdominal pain, lower abdominal heaviness, a sense of needing to defecate, sometimes severe pain accompanied by profuse sweating.
3. Vaginal bleeding, usually in small amounts.
4. Other symptoms may include nausea, vomiting, and frequent urination.
5. Examination: A positive pregnancy test, ultrasound scan, or laparoscopy can assist in diagnosis.
6. Symptoms of ectopic pregnancy are often atypical. Some patients may experience shock due to severe bleeding, with pale skin and declining blood pressure. In such cases, ectopic pregnancy should be considered, and timely treatment is essential.
