Multiple pregnancy
A number of twin gestations have occurred where each uterus carried its pregnancy separately. It is possible that the deliveries occur at different times, thus the delivery interval could be days or even weeks.
Triplets
A UK woman with a double uterus gave birth to triplets in 2006. Hannah Kersey, of Northam in Devon, gave birth to a pair of identical twins from an egg that implanted into one womb and then divided, and to an infant from a single egg that implanted into the other womb. This was the first known birth of viable triplets in a woman with a double uterus.[5]. It is estimated that the possibility of such a birth is about 1 in 25 million.[6] A triplet pregnancy in a woman with uterus didelphys was reported from Israel in 1981; one baby died in utero, and of the remaining babies, one was delivered at 27 weeks gestation and the other 72 days later.[7]
