Conception can be detected with an early pregnancy test around 2 weeks.
When a woman has intercourse, if she happens to ovulate, the egg combines with the sperm to form a fertilized egg, which will settle in the uterine cavity and will eventually develop into a fetus. You can usually detect it with an early pregnancy test after about 3 weeks of intercourse. When checking with early pregnancy test strips, use morning urine and operate in a standardized manner to avoid errors in the results.
The HCG value in the blood is the first to rise when a woman is pregnant, and will then gradually appear in the urine. Due to individual differences, the hormone levels in the body after conception are different, not all women will definitely find out if they are pregnant two weeks after intercourse, and the safer time to measure is after the menstrual period has been postponed for 7-10 days, at which time the results are more accurate.
