Stange Pregnancy

I watch a show tonight called "Strange Pregnancy" on Discover Healty....It was so weird. If you didn't watch it here is a summary.

There was basically 3 stories:

1. A lady had a baby develop outside of her womb, just floating around in her abdominal cavity. She had a womb, the baby just decided it did not want to grow inside her womb.

2. A 55 year old grandma carried a pregnancy for her daughter and she ended up having triplets. The daughter could not conceive since she had a hysterectomy (she had two children from a previous marriage who were now teens I believe) but she and her new husband wanted a baby, so the grandma carried her egg and hubbies sperm.

3. The third story was about a girl who had 2 uteruses (uteri ?) and she became pregnant in both at the same time. She released 2 eggs, one in each uterus, and both became babies.
