An Alabama woman gives birth to a pair of girls after a "one-in-a-million" dicavitary pregnancy.

Kelsey Hatcher, 32, delivered one daughter on Tuesday, and a second on Wednesday, at the University of Alabama at Birmingham (UAB) Hospital.

Announcing the arrival of her “miracle babies” on social media, Ms Hatcher hailed the medics as “incredible”.

The girls are described as fraternal twins - with rare separate birthdays.

Hatcher said the family was now back at home and could “enjoy the holidays”. She had previously expected a Christmas due date.

The mother was told at age 17 she had a double uterus (uterus didelphys) - which the UAB described as a rare congenital anomaly affecting 0.3% of women.

And the odds of becoming pregnant in both uteri - a dicavitary pregnancy - were even slimmer, at “one in a million”, according to the UAB.

    I suspect that it would be impossible to get a 2nd pregnant after a couple of weeks of the first. The baby produces hormones that stop ovulation. The 2nd one would have to be in before that window.

    I also suspect that the birth of the 1st would induce the second. She likely didn’t leave labour, the 2nd just took longer, since it was, effectively, induced by the first.

    Going back to the broader question, it’s likely that both were inside the mother at the same time. In theory they could be 9 months apart, though that would likely require significant medical effort, and so is effectively impossible.
