Scared a bunch of you, didn't I?

Anybody watch those TLC shows about women who never knew they were pregnant......go into labor and deliver a baby either in their home or at the hospital emergency room?

I will never understand how on earth someone could not know they were pregnant. For the entire nine months nothing hinted to the fact that you had a full term baby growing inside you? I'm sure it happens but I just don't buy the story that nothing changed with their bodies the entire time.
