Oh God: A one-year-old girl in Saudi Arabia is pregnant. As in, there is a fetus in her uterus. Apparently it's a strange case of absorbed sibling, in which a fetus absorbs its twin while in the womb. In this case, it seems, the twin grew inside her sister, who was then born with her sibling's fetus in her uterus. [Strollerderby]
When my mother was pregnant with me, they did an ultrasound and found she was having twins. When they did another ultrasound a few weeks later, they discovered, that I had resorbed the other fetus. Do I regret this? No, I believe his tissue has made me stronger. I now have the strength of a grown man and a little baby.
