Woman falls pregnant twice in 10 days
An Australian woman who was told she might never become pregnant says she has given birth to twins conceived 10 days apart.
Kate Hill was receiving hormone treatment for polycystic ovary syndrome, a condition that meant she was not ovulating.
She apparently conceived twins at different times despite only having unprotected sex once during that time.
It is very rare for a woman to conceive a second time when already pregnant.
Most twins are the result of a woman releasing two eggs at the same time, or, less commonly, a fertilised egg subsequently splitting into two.
The twin girls, Charlotte and Olivia, were born 10 months ago with different sizes, weights and gestational development, according to reports.
"We actually did not realise how special that was until they were born," Mrs Hill told Australia's Seven Network.
