How should ectopic pregnancy be detected?

Ectopic pregnancy can be detected by color Doppler ultrasound, progesterone, and human chorionic gonadotropin levels in the blood. A pregnancy sac can be seen outside the uterus on color Doppler ultrasound, and progesterone and human chorionic gonadotropin levels are low. After menopause, vaginal bleeding, abdominal pain, and bloating can occur.
