Breast tenderness, which occurs a few days after conception. Bleeding during implantation, etc. 2. Serum human chorionic gonadotropin level: usually in the second week after the transfer of serum human chorionic gonadotropin, the hormone rises to a certain level to determine whether the embryo transfer is successful. 3.
