Participants will be educated on CGM use and have the continuous glucose monitor (CGM) placed by one of the investigators experienced in CGM use. The monitor will remain in place for 72 hours and will record blood glucose levels every 5 minutes. During this time, patients will continue their usual medical routine, including SMBG and fetal surveillance. After 72 hours the patient will return to the office to have the CGM removed and the data will be downloaded and analyzed. Patients that have not had a HbA1C sent within the last 4 weeks will have one drawn (standard of care). To determine whether 72 hours is long enough to obtain accurate information, 10 participants in each group (cases and controls) will be asked to wear the CGM for a second 72 hour period, and the results of the second 72 hours will be compared to the first for that participant.
