The term transfer refers to embryo transfer, and the vague pain in the stomach after embryo transfer is usually normal, but it can also be caused by infections and ovarian hyperstimulation syndrome, and should be taken seriously. After the transfer procedure, patients may experience a vague pain in the stomach and bloating, which is a more common reflection. This is mainly due to the irritation of the uterine wall caused by the growth of the gestational sac, so it is normal to have vague pain in the stomach after transplantation. However, if the pain is more obvious, it is necessary to pay attention to whether it is caused by postoperative infection or ovarian hyperstimulation syndrome. Other relevant examinations should be combined to determine the cause and provide appropriate treatment. Clinical patients with vague stomach pain after embryo transfer should go to the hospital in time to avoid adverse consequences.
