2. The Woman Who Got Pregnant Twice in 10 Days
In 2006, doctors diagnosed Kate Hill with an ovary disorder and told her she might never be able to get pregnant. Rather than accept her fate, the Brisbane, Australia, resident doubled down. In 2015, she conceived twice, 10 days apart. Her daughters aren’t technically twins but rather the products of a rare phenomenon called superfetation—a conception during an ongoing pregnancy. Doctors aren’t entirely sure how it happened, especially in light of the fact that Hill only had unprotected sex once within that time frame. The unconventional conception will no doubt make for an interesting conversation when the girls are old enough to ask where babies come from.
