Caroline Wortman, 30, from Woodstock, Georgia, was told that she may be infertile after being diagnosed with uterine didelphys – meaning she was born with two reproductive systems.
However she gave birth to daughter Josie in January 2021, and six months after her birth, discovered she was already expecting another baby.
After learning she was pregnant again, she said she and her husband Nate were baffled, adding: ‘We were giggly with excitement but also still terrified.’
While her pregnancy was normal, she went into labour at 33 weeks and five days and the couple welcomed their son, Brooks, on Boxing Day 2021.
Caroline was 18 when she had her first appointment with the gynaecologist who, after completing the exam, told her that she had two cervixes.
Uterine Didelphys is caused because when a female foetus is growing, the uterus starts out as two small tubes called Müllerian ducts.
These will eventually fuse together to form the reproductive system in a process called embryogenesis.
Women with uterine didelphys do not undergo full embryogenesis, and can be born with two full reproductive systems.
She said: ‘I honestly shrugged it off because I didn’t really realize what the implications could be.
