MAYBE BABY: 18-YEAR-OLD GIRL DOESN'T KNOW SHE IS PREGNANT, FINDS OUT IN A SHOCKING WAY!

A 'small' size Border Force student was shocked when she went into labour during riot training bcause she had no idea she was pregnant.

Beth Martin, 18, from St Anne's, Blackpool, was training to become part of the UK's Border Force, and undertaking extreme physical activity such as army and police riot training up to only an hour before she entered labour, reports Daily Mail.

Known as a 'cryptic pregnancy', Beth's baby Maizie, now seven-months-old, had grown behind her mother's ribs, showing no physical bump - and had even failed to show up on two pregnancy tests. She maintained a slim figure throughout pregnancy.

'By the time I got to the hospital I was in so much pain,' explained Beth. 'A nurse told me straight away I looked pregnant - and then I discovered I've been in labour for 69 hours.'

'I'd never wanted to have kids but now I can't imagine my life without her.

'My dad was so happy, and my mum came after, shaking her head - we were all in shock. Yet I've absolutely loved becoming a mum - Maizie is the best thing in my life.

'I went back to college in September to complete my course and back to work after just thee months off on maternity leave. I wanted to show people what else I can achieve - and I'm prepared for anything.'
