Patient's question:
How many days after sexual intercourse can an early pregnancy test detect pregnancy? I have been 10 days since sexual intercourse and the test has not shown a positive result.Doctor's answer:
Generally, a pregnancy test can be detected one week after a missed period or ten days after intercourse. This is because HCG starts to be secreted only after the fetus implants, which is why it can be detected. To achieve higher accuracy, morning urine should be used for the test. Morning urine is the best, as the body has accumulated urine overnight, resulting in a higher concentration of HCG in the urine at this time. Early pregnancy test strips are most sensitive at this stage. The accuracy of early pregnancy test strips is not 100%, so if pregnancy is detected, it is recommended to go to the hospital for a B confirmation.
