Can a delayed period by two days indicate pregnancy?

Patient's question:

No

Doctor's answer:

Menstrual cycle delayed for 7 days or after 10 to 14 days of intercourse, a pregnancy test can be detected with early pregnancy test strips. Two red lines appear on the test paper, indicating a positive result, which means pregnancy. Additionally, 7 days after sexual activity, you can go to the hospital for a blood HCG test, which is the most accurate method for detecting pregnancy.
