An Australian woman conceived two baby girls 10 days apart. Yes, you read that right, she had sex one time and got pregnant and then got pregnant again 10 days later.
Kate and Peter Hill have two beautiful baby girls that resulted from polycystic ovarian syndrome which is a hormonal condition that left her unable to ovulate back in 2006. When she wanted to get pregnant earlier this year, doctors prescribed hormone injections to help her conceive.
Conceiving a second child while already pregnant, aka superfetation, is so rare that there are reportedly only 10 or 11 known cases in the world. Kate was quoted as saying “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.”
