A 40 year-old woman, Amanda Morgan, who was diagnosed with early menopause, gave birth to a little girl the same day. Amazingly she was actually 6 months pregnant and the little baby girl, Caitlin, spent 5 weeks in the hospital. Mom and daughter are doing fine and Caitlin will be turning 1 this February.
There have been stories over the years when women did not know that they were actually pregnant until they went into labor. Morgan was actually in the bathroom and with one push baby Caitlin came out and surprised her mom and dad.
