Kate Hill’s pregnancy was so unusual the birth of her baby girls has been hailed a miracle. 

In 2006 Mrs Hill has diagnosed with polycystic ovarian syndrome: a hormonal condition that left her unable to ovulate.

She underwent hormone treatment and fell pregnant, not once, but twice.
Kate Hill was told she may never conceive due to a condition she had known as  polycystic ovary syndrome, but she defied nature and doctors predictions by conceiving twice in 10 days, making medical history.

Healthline describes Polycystic ovarian syndrome, or PCOS, is a condition in which a woman’s levels of the sex hormones estrogen and progesterone are out of balance. This leads to the growth of ovarian cysts (benign masses on the ovaries). PCOS can cause problems with a women’s menstrual cycle, fertility, cardiac function, and appearance.


Kate and her husband Peter soon found out they were pregnant with two babies, conceived at different times, even though the couple say they only had unprotected sex once and Kate went under a series of hormone drugs. In an interview with Today Tonight Adeleaide Kate says:

“What makes this case even more rare, is that my husband and I only had intercourse one time – his sperm stayed alive for 10 days to fertilize the second egg released, We actually didn’t realize how special that was until they were born Usually a woman doesn’t ovulate once they’re pregnant with all the hormones, but Charlotte was coming no matter what.”Mrs Hill

Getting a double pregnancy is so rare that her OBYGN confesses that she had never encountered it before. The non-identical twins, Charlotte and Olivia, are healthy 10 month olds with different blood types and different personalities Kate shared.

It was a medical phenomenon so rare there are only 10 medically documented cases of it in the world.


Mrs Hill conceived two babies, 10 days apart. The conception is called superfetation, which essentially means she fell pregnant while already pregnant.

The rare conception started as a single pregnancy with twins, before she conceived again 10 days later to be pregnant with triplets.

Sadly the couple lost one of the babies early on in the pregnancy, and the Hills were given two due dates – December 20 and December 30 2015. Their adorable girls, Charlotte and Olivia, were born together two days before their scheduled caesarean.

The girls measured very differently in size, weight and gestational development. They are now 10 months old, and their loving parents told Today Tonight they have different blood types.
