Utah resident Angie Cromar has a rare condition called uterus didelphys, which means she has a double uterus. And right now, there's a baby in both of them, each at different stages of development. One is five weeks and four days along; the other is six weeks and one day along, reports ksl.com, the website of NBC affiliate KSL-TV 5 in Salt Lake City.
Although pregnancy in both uteruses is rare -- the chances are about 1 in 5 million -- this isn't the first recorded case. Nor is it the weirdest. In 1981, a woman with uterus didelphys became pregnant with triplets, two in the left uterus, one in the right. Babies on the left were delivered on the same day, two hours apart; baby on the right was delivered 72 days later. And in 1961, a woman with two uteruses, two cervices and two vaginas delivered two healthy babies. But even women without uterus didelphys can become pregnant with twins-that-aren't-twins. Last year, an Arkansas woman named Julia Grovenburg conceived while she was already pregnant, an example of a rare condition called superfetation.
