Patient's question:
Menstruation is delayed by 18 days and has not arrived yet. Since the 5th day of the delay, tests have consistently shown one line. Today is the 18th day of the delay, and in the morning, an early pregnancy test using first-morning urine also showed one line.Doctor's answer:
The possibility of pregnancy is relatively low, but it cannot be completely ruled out. It is best to go to the hospital for a blood HCG test. Blood HCG testing is quite sensitive and has high specificity. If a blood HCG test is done, pregnancy can be detected 8-10 days after intercourse. If the blood HCG test is also negative, it can be basically ruled out that pregnancy is not possible.
