Conjoined twins are extremely rare. But something even more rare than conjoined twins is conjoined twins getting pregnant and giving birth. Recently, famous conjoined twins Abby and Brittany Hensel sparked pregnancy speculation by posting a TikTok of the wildest gossip news about their lives. While I don’t know if they’re actually pregnant, it did get me thinking – do we have ANY documented cases of conjoined twins successfully conceiving and giving birth? Turns out we do, but just one. It’s from the early 1900s, it stars two sisters who became circus performers, and you will NOT believe how wild their pregnancy story was.
