Physician appointment may vary from patient to patient, depending on certain risk factors. Generally, you will have monthly visits until 28 weeks, then visits are every two weeks up to 36 weeks; and then visits are weekly until delivery. We always try to follow our office schedule, but please understand that if a baby needs to be delivered or an emergency arises, you may have to wait, or your appointment may need to be rescheduled. Please accept our apologies.
