What are the symptoms of ectopic pregnancy, and how can you know if you have one?

Patient's question:

No

Doctor's answer:

No obvious abnormal symptoms in early pregnancy. If there is an ectopic pregnancy and the gestational sac ruptures, early symptoms are only a small amount of vaginal bleeding, intermittent, accompanied by mild abdominal pain. It can be confirmed with an ultrasound at 40 days of pregnancy.
