If you had the same room last month, can you test whether you are pregnant this month?

Patient's question:

No

Doctor's answer:

If using a pregnancy test, it is generally possible to detect pregnancy 1-3 days after a missed period, with the earliest detection possible 3-4 days before the period. If undergoing a quantitative blood HCG test at a regular hospital, pregnancy can typically be detected about 10 days after intercourse.
