Patient's question:
What is the minimum number of days pregnant you can be to test positive?I don't know if I'm pregnant, as my period, which usually comes a few days early, hasn't arrived in three days yet...
Doctor's answer:
Hello, after fertilization, a small amount of HCG begins to be secreted 6-7 days later. Sperm can survive in the female reproductive tract for 2-3 days, and the egg can survive for 1-2 days after being released, waiting for fertilization. If you have intercourse two to three days before ovulation, you will need to wait at least 10 days or more after the intercourse that led to pregnancy before you can take a pregnancy test. A significantly elevated blood HCG level is the gold standard for diagnosing early pregnancy. Generally, 10 days after intercourse, you can go to the hospital for a blood test. Pregnancy test strips can also be used.
