How long after pregnancy can it be detected?

Patient's question:

No

Doctor's answer:

Generally, early pregnancy tests can be used to detect pregnancy after a delay of 7 days in the menstrual cycle or 10 to 14 days after intercourse. Two red lines appearing on the test paper indicate a positive result, meaning pregnancy. Additionally, after 7 days of sexual activity, blood HCG tests can be conducted at the hospital for more accurate results.
