A woman in Great Britain gave birth to identical twins from one womb and another baby from her second womb.
Some info from the article:
Only 70 women are known to have been pregnant from 2 wombs.
One in one thousand women have this double/split uterus in the UK.
The chances of a woman with two wombs having twins or two separate births is estimated to be five million to one.
The odds of having triplets from two wombs are around 25 million to one.
