Woman Stops Running Half Marathon - Gives Birth - Didn't Know She Was Pregnant

A woman in Minnesota who has three kids already was training for a half marathon when she stopped because her back had started to hurt. It turns out it was labor pains and five minutes after she got to the hospital in Duluth she gave birth. The woman said she had not gained weight and had felt no movement for the entire pregnancy and never even suspected she was. An even bigger shock might have been from the her husband who had previously had a vasectomy. The woman is just 33. I'm assuming she had been having her period until she got pregnant. Did she not think it was odd that she went 9 months without getting it? I always find these stories hard to believe, but I guess anything is possible. I mean Kim Kardashian is famous.
