After ten days of transplantation, the secretion becomes more, if the color of the secretion is transparent and odorless, it is a normal phenomenon. If it is brown with odor, it is an abnormal phenomenon, which may be caused by vaginitis, blastocyst implantation and failure of blastocyst implantation. 1. Normal phenomenon: after transplantation, due to the change of sex hormone level in the body, resulting in the increase of secretion, if the color of the secretion is transparent, and there is no odor, it is a normal situation. 2. Vaginitis: the secretion becomes more after ten days of transplantation, if the secretion has odor or is bean dregs-like or purulent leukorrhea, accompanied by vulvar itching, it may be caused by vaginitis. 3. Blastocyst implantation: if the secretion is brown and disappears soon after ten days of implantation, it may be that the blastocyst has successfully implanted. 4. Failure of blastocyst implantation: if the secretion is brown after ten days of implantation and the amount increases gradually, it is considered that after the failure of blastocyst implantation, the hormone in the body decreases, leading to the shedding of endometrial lining, which leads to the manifestation of menstruation. It is recommended that patients who have more secretions after ten days of implantation should go to the hospital in time to do relevant examinations to clarify the cause of the disease, so as to avoid delaying the disease and causing adverse consequences.
