A referral to a maternal-fetal medicine (MFM) specialist — also called a perinatologist — does not mean something is wrong. It means your pregnancy benefits from the expertise of a physician with advanced training in managing complex pregnancies.
MFM specialists typically have 3 additional years of fellowship training beyond obstetrics and gynecology residency. They specialize in advanced ultrasound interpretation, genetic counseling, managing chronic conditions during pregnancy, and coordinating multidisciplinary care.
In many cases, the MFM works alongside your regular OB or midwife. The MFM handles the high-risk aspects (specialized ultrasounds, condition management, delivery planning), while your OB manages routine prenatal care. Some people see their MFM only a few times during pregnancy; others see them frequently. It depends on the complexity of your case.
