How soon after intercourse can you know if you are pregnant? – Dr. Teena S Thomas

Basic hormone which is required to say that a girl is pregnant is HCG human chorionic gonadotrophin so when HCG is positive and that is when we say pregnancy, basically HCG positive can be seen on in the blood and in the urine in the blood anything about 5 units is pregnancy, in the urine anything about 25 units can be seen. So a urine pregnancy test is expected to be positive when the cycles a regular to be 2 weeks after the intercourse. So if you had sex today 2 weeks from today during pregnancy test is supposed to be positive, but a negative urine test doesn’t mean that it is always negative positive is positive but a negative doesn’t mean because if after the egg is released it can stay for 24 hours to 48 hours and the sperm can stay to 72 hours rarely up to 7 days also. So a delayed pregnancy can still show positive during pregnancy test is usually positive 2 week from intercourse and a blood test can be positive a little earlier maybe 11, 12 or 13 day your blood test can be positive.
