When should David test the early pregnancy test?

Patient's question:

No

Doctor's answer:

Generally, 8-10 days after sexual intercourse, you can confirm whether you are pregnant by a blood test to check HCG. This is currently the earliest and most accurate method. After a 7-day delay in the menstrual cycle, you can use a home pregnancy test. If two red lines appear on the test paper, it indicates a positive result, meaning you are pregnant.
