Visit 2 - the day of the fecal transplant: This visit will take about 4-6 hours. A pregnancy test will be repeated. If the pregnancy test comes back positive for a patient who is younger than age, both the patient and parent will be informed. The study doctor will ask you and the donor how they are feeling. If either the patient or the donor is not feeling well, the transplant will be reschedule to another day. If both are well, the fecal transplant will proceed.
