A woman with a uterine didelphys, or double uterus, is carrying a pregnancy in each uterus, ABC reported Nov. 13.
While uterine didelphys is rare, the odds of being pregnant in each uterus at the same time is "1 in a million," Richard Davis, MD, a maternal and fetal medicine specialist at the University of Alabama at Birmingham's Women & Infants Center, told ABC.
Kelsey Hatcher, a 32-year-old mother of three, is currently about 34 weeks pregnant with a due date of Dec. 25. Dr. Davis said they plan to allow Ms. Hatcher to carry her pregnancy as long as both she and the babies are healthy.
Dr. Davis and Shweta Patel, MD, an OB-GYN, are caring for Ms. Hatcher and the fraternal twins.
"There's no true expert out there who knows how to manage a patient with two uteruses and two babies, with one in each uterus," Dr. Patel told ABC. "So we really are relying on our baseline teaching and our baseline knowledge and the normal physiology of pregnancy that we understand, and applying it in her scenario."
It is uncertain how the delivery will go.
"They could be born minutes apart, or they can be born days apart," Dr. Patel said. "It's so unpredictable, and that's why we've had a lot of conversations with Kelsey kind of talking about the different scenarios that could happen, where she could have a vaginal delivery with both babies, she could have a vaginal delivery with one and a C-section with the other, or maybe end up having a C-section for both of them as well."
