If you do not feel anything after the transfer, it is possible that the transfer time is too short and there is no pregnancy reaction yet, which is a normal phenomenon and there is no need to worry. Generally about 1-2 days after the transfer, the embryonic tissues will implant in the uterus. During the process of implantation, only a few women who are more sensitive will experience mild vague pain in the small abdomen or a small amount of vaginal bleeding. The symptoms will usually fade away in about 1-2 days and most of them will not feel anything. Two weeks after transplantation, with the increase of human chorionic gonadotropin secretion in the body, which causes the decrease of gastric acid secretion, gastrointestinal reactions, also known as pregnancy reaction symptoms, will occur. The severity of the reaction varies with the physical condition of each pregnant woman. Most of the symptoms of pregnancy reaction are mild and may include fatigue, dizziness, nausea, vomiting and aversion to fatty food.
