Incarcerated Uterus

Her uterus was retroflexed (aimed backwards).  During the first trimester of pregnancy her womb, still tipped back, grew into the curved space in front of the sacrum and tailbone under the sacral promontory. The uterus is not up in the abdomen at all!

Once upon a time, a doctor wrote about this rare condition and used the phrase, "incarcerated uterus." Wikipedia
