You can eat if you are hungry after a blastocyst transfer. The person is awake during the blastocyst transfer procedure, there is no need for anesthesia, and there is no question of needing to fast for a period of time after anesthesia, so it is possible to eat after blastocyst transfer if you feel hungry. After blastocyst transfer women can stay in the hospital for 15~30 minutes for quiet observation and then leave the hospital. 14~16 days after the transplantation, you need to go back to the hospital to take blood test for HCG to determine whether the pregnancy is successful or not. In order to avoid complications and promote successful pregnancy, patients should pay attention to observing their own situation and do a good job of life care, such as reasonable diet, moderate exercise, work and rest, maintain a happy mood, and live regularly.
