Blood test showed pregnancy six days after intercourse.

Pregnancy blood tests are often inaccurate six days after intercourse, as the results may be interfered with by hormone fluctuations or other factors. Blood tests to detect pregnancy need to be conducted at least 10-14 days after intercourse, when the level of human chorionic gonadotropin in the blood reaches the detectable range.

Six days after intercourse, the fertilized egg may not have completed implantation, and the level of human chorionic gonadotropin in the blood is extremely low, making it difficult to accurately identify it with conventional testing methods. Some women may have false positive results due to luteal insufficiency or abnormal hormone secretion. Premature detection may also be affected by physiological or pathological factors such as recent ovulation drug use and ovarian cysts.

In rare cases, the embryo implantation time is advanced or the detection equipment is extremely sensitive, a weak positive result may be detected, but this situation requires a review of human chorionic gonadotropin doubling 48 hours apart to confirm. Abnormal pregnancy conditions such as ectopic pregnancy and biochemical pregnancy may also lead to abnormal early detection results.

It is recommended to use morning urine for early pregnancy test paper after one week of delayed menstruation, or go to the hospital to draw blood to test human chorionic gonadotropin 14 days after having sex. During pregnancy preparations, you should maintain a regular schedule, avoid smoking and drinking, and take a daily supplement of 0.4 mg folic acid tablets. If you are diagnosed with pregnancy, you need to have prenatal check-ups on time, and avoid strenuous exercise and heavy physical labor in the early stages of pregnancy.
