How many weeks of pregnancy can an ultrasound detect?

Patient's question:

No

Doctor's answer:

Hello, around 6 weeks after pregnancy (pregnancy duration starts from the first day of the last menstrual period), you can go to the hospital for an ultrasound examination to confirm whether you are pregnant. It is recommended to have a blood HCG test at the hospital 7-10 days after intercourse, which can clearly determine whether you are pregnant, and the results are very accurate.
