Patient's question:
How long after sex can you usually find out if you are pregnant? Also, do you still get your period after getting pregnant? What causes the period to appear black and in small amounts?Doctor's answer:
Generally, it is recommended to use a test strip 14 days after sexual activity and a blood HCG test 7 days later to confirm pregnancy. It is advised to use an early pregnancy test strip for an initial detection to observe whether it is negative or positive. If it is negative, it will show one line, indicating no pregnancy. If it is positive, it will show two lines, indicating pregnancy. There may be some errors when using an early pregnancy test strip. The best method is to go to the hospital for HCG blood tests, HCG urine tests, and ultrasound examinations to confirm whether pregnancy has actually occurred.
