Besides pregnancy tests, are there other methods to confirm pregnancy?

Patient's question:

No

Doctor's answer:

After a one-week delay in the menstrual cycle, an early pregnancy test can be used to detect it. If two red lines appear on the test paper, it indicates a positive result, meaning pregnancy; alternatively, you can go to the hospital to have your blood tested for human chorionic gonadotropin (hCG) to confirm whether you are pregnant.
