Conception can usually be detected with a pregnancy test 7-14 days after conception.
After the fertilized egg is formed, it will gradually move to the uterine cavity and implant, after the implantation is successful, as the embryo continues to develop, the trophoblast cells of the placenta will secrete a large amount of HCG (human chorionic gonadotropin), which enters the bloodstream and urine, and the pregnancy test is used to predict pregnancy through the detection of HCG in the urine of the woman.
Generally, the fertilized egg will not attach until about 6-7 days after conception, so pregnancy can be detected by the pregnancy test in about 7-14 days. If the test is positive, you can go to the hospital for blood HCG and ultrasound test to further confirm whether you are pregnant.
It is recommended to consult a doctor for standardized treatment if necessary.
