Pregnancy can be detected by taking a blood test around 10 days, but it is impossible to generalize due to individual circumstances.
When a woman of childbearing age engages in unprotected sex, if the egg and sperm combine to form a fertilized egg, it can usually be deposited in the uterine cavity in about a week. At this time, the trophoblast cells of the embryo will gradually secrete human chorionic gonadotropin (HCG), which can be detected by blood test in about 10 days to ascertain whether or not a woman is pregnant.
Some pregnant women, due to individual variability, may need to delay the detection of pregnancy for some time. After the blood test, an ultrasound should also be performed as prescribed by the doctor to find out if the pregnancy is intrauterine.
Pregnant women need to keep the perineum clean and dry and avoid intercourse during early pregnancy.
