WASHINGTON – A 32-year-old woman from Alabama who was born with two uteruses and became pregnant in both gave birth to twin girls on different days, she announced on Dec 22.

“Our miracle babies were born!” Ms Kelsey Hatcher, who is documenting her story on her Instagram account, “doubleuhatchlings”, wrote in a post.

She said the girls “decided they were rare enough statistically that they should just go ahead and have their own birthdays too”.

The first one, named Roxi Layla, was born on Dec 19 at 7.49pm. She was joined by Rebel Laken on Dec 20 at 6.09am.

Doctors had estimated a Christmas due date, but the sisters arrived just in time to be at home for the holidays with their siblings.

The mother and daughters have been discharged from hospital, with Ms Hatcher promising to share details about the delivery in future.

Ms Hatcher knew from the age of 17 that she has “uterus didelphys”, a rare congenital condition thought to affect only about 0.3 per cent of people born female.

It was during a routine eighth-week ultrasound visit in May that the massage therapist and then mother of three learnt not only that she was having twins this time, but that a foetus was present in each of her uteruses.

Pregnancies in both uteruses are exceedingly rare, according to Dr Shweta Patel, the obstetrician-gynaecologist who cared for Ms Hatcher at the University of Alabama at Birmingham’s Women & Infants Centre.

Ms Hatcher said she was told the odds were one in 50 million – with the last widely known case occurring in Bangladesh in 2019 when Ms Arifa Sultana, then 20, gave birth to healthy twins 26 days apart. AFP
