When health care assistant Karen Barker, 24, visited her GP with a bloated tummy, she expected to be told she had a bowel problem, yet the doctor gave her a far more shocking diagnosis - she was eight months pregnant.
Karen, 24, was then in for a further surprise when just 24 hours later she suffered stomach pains whilst at work and gave birth at her local walk-in health centre.
Karen, from Sunderland, who already has a one-year-old son Jamie-Lee, said she had no idea she was pregnant when she first visited the doctor.
'I experienced none of the signs I had with my first pregnancy so had no idea I was expecting. I worked all the way through the pregnancy doing 12-hour shifts with lots of lifting and bending. I was always tired at the end of the day but I thought nothing of it.'
Nurse Nicola Trewick, who helped deliver the baby - a 6lb 8oz boy named Jack - at the NHS walk-in centre said that staff there usually only dealt with minor injuries.
She said: 'It was incredible to be involved in such a marvellous experience.'
Karen and baby Jack went home after a night's observation in a local hospital.
