I watched an episode years ago, I think it was either Regis & Kathy Lee or Oprah, and this woman and her hubby were out dining, she was a professional singer and was up on the piano doing her thing when she went into extreme pain and was rushed to the hospital.
They told her she was going into labour.
Now this woman looked about 5'8 and was maybe 130lbs and she said that how she looked that day was just how she looked the day she gave birth!
Her breasts didn't get larger, her stomach did not grow, she had her period the whole pregnancy and she NEVER had any idea!
The baby was healthy. I don't remember what they said the weight of the baby was!
But can you imagine?

It's one of those - I'd have to see it happen to believe it - type of things!
