Millie-An's position is thought to be the result of an extremely rare form of ectopic pregnancy - in which the egg develops outside the womb. Normally in such cases the fertilised egg implants itself in one of the fallopian tubes on its way to the womb.
But it can also fall out the tube and implant anywhere in the abdomen.
Wait a minute...

It happens when there is a structural problem in the mother's tubes (like a hole or the end does not attach properly), and is more common than you would think --- usually just resulting in repeated miscarriages (or failure to fertilize).
It's nothing odd sexually going on, if that is what you were thinking.
