Imagine having a condition so rare that your own doctor had to Google it.
That's what happened to Kate Hill when she got pregnant not once but twice in the span of 10 days. Kate and her husband, Peter, had been trying to conceive for some time when she began hormone therapy. Then something crazy happened.
After having unprotected sex just once, Kate conceived twins. However, one of the them was non-viable. A few days later, she ovulated -- something that normally doesn't occur in pregnant women. Incredibly, she conceived for a second time.
Kate Hill didn't set out to make medical history, but that's exactly what she did. Conceiving while already pregnant, known as "superfetation," is so rare, there have only been 10 documented cases in the world.
Doctors couldn't believe what they were seeing. One of the physicians told Today Tonight that he had to "Google it."
Although the girls were given due dates 10 days apart, they arrived together two days before their scheduled cesarean. They had different weights, lengths, and even blood types, but both were healthy.
Today, Charlotte and Olivia are 10 months old! The girls are considered twins, but how they made their way into the world is a story that their parents and the medical community will be telling for years to come.
