Patient's question:
Good friend is 28 years old, her period has been delayed for more than ten days, and she doesn't know if she is pregnant, quite nervous. Please ask: How many days after intercourse can you know if you are pregnant?Doctor's answer:
Consider using a test strip to monitor the data around a 10-day delay in menstruation, or simply go to the hospital for an hCG test to check for clarity. Testing can be done 7-10 days after sexual intercourse, of course, the longer the time, the more accurate it is. The working principle of early pregnancy test strips for self-testing is to detect the HCG value, which is the value of human chorionic gonadotropin. This hormone is produced by the placenta and generally appears in the urine a few days after pregnancy, but due to its small amount, it has become increasingly difficult to detect until about 10 to 14 days.
