Patient's question:
My sister previously had an ectopic pregnancy, and now she is pregnant. She is also worried. How long after pregnancy can an ectopic pregnancy be detected?Doctor's answer:
Pregnancy can be detected around 6 weeks. If the menstrual cycle was previously normal and regular, at around 6 weeks of pregnancy, a transabdominal color ultrasound can reveal a gestational sac within the uterine cavity. If a color ultrasound at 6 weeks shows no gestational sac in the uterine cavity, along with symptoms such as abdominal pain or irregular vaginal bleeding, it is necessary to check the blood hCG levels. Based on the blood hCG levels, combined with clinical symptoms observed through color ultrasound, it can be confirmed whether the pregnancy is ectopic.
