How long after conception can you detect

Pregnancy is usually detected at 7-14 days or 4-5 weeks after conception by various tests.

Pregnancy can be detected earlier by blood tests than urine tests, usually 7-10 days after conception. Blood tests are more accurate and can reflect pregnancy more sensitively. Urine Detection Tools such as pregnancy sticks generally do not detect pregnancy until 10-14 days after conception, when urine levels of human chorionic gonadotropin gradually rise to detectable levels. However, individual differences may lead to slightly different detection times. If the detection is too early, false negative results may occur. Generally, 4-5 weeks after conception, transabdominal ultrasound may see the gestational sac, and transvaginal ultrasound may see it earlier. Ultrasound can not only confirm pregnancy, but also determine the location and size of the gestational sac. It is important to rule out abnormal conditions such as ectopic pregnancy.

If there are doubts about pregnancy or special circumstances, it is recommended to consult a doctor in time for more accurate diagnosis and advice.
