A mother-of-one has appeared on television to reveal what being trapped in a real-life Groundhog Day really feels like.

Nikki Pegram, 28, from Wellingborough in Northamptonshire, wakes up every day believing that it is the 15th October 2014 - and has to be reminded daily of all that has happened since.

Boyfriend Chris Johnston, a 39-year-old groundskeeper, has to explain that she has amnesia every morning and bring her up-to-date with everything that has happened during the last nine months.

TV: She told her story on This Morning and said losing nine months of your life is 'scary'

Ms Pegram's problems began last autumn, when she was booked in for a routine knee operation on the 15th October.

Disoriented after the procedure, she tripped and hit her head on a metal pole - and has relived the same day repeatedly ever since.

'I remember being given the results of the X-ray and nothing after that,' she said during an appearance on ITV's This Morning.

When Mr Johnson arrived to collect her from the hospital, he discovered her lying on the pavement outside Kettering General Hospital surrounded by medics.

'I got a text message and by the time I got there, she was lying on the floor unconscious,' he remembers.

'Nobody is quite sure what happened. They think she fainted from the pain [of her knee] and smacked her head on a metal railing going down.'

Rushed back inside, she was treated for severe head injuries and a seizure by doctors but woke up the next day believing it was still the 15th October.

Subsequently diagnosed with short term memory loss, she remembers nothing that has happened since the accident, including her 28th birthday and Christmas.

She has also missed out on much of her five-year-old son Freddie's life, including new achievements, and has to be told each day that one of her pet cats has died.

'I used to talk her through it in the morning and it took around two hours,' explains Mr Johnston. 'She used to think I was winding her up.'

Now Ms Pegram, who managed a pub before her accident, uses a memory pad to get by but still finds shopping and family holidays challenging.

No cure: Doctors say there's a chance that she might recover but she could also end up with amnesia for life

On a recent caravan holiday in Skegness, she woke up terrified each morning and utterly baffled to find herself sleeping in an unfamiliar place.

'She expected to wake up at home in bed but she woke in a caravan,' says Mr Johnston. 'I made sure she didn't wake alone but she was basically having a panic attack.'

While the couple are hopeful that her memory might one day recover, they are resigned to the prospect of Ms Pegram reliving the same day over and over again forever.

'The doctors have said it might come but then again, it might not,' explains Mr Johnston.

Ms Pegram added: 'It's very upsetting because there's so much that I've missed. Christmas, family birthdays and so on.

'Waking up every day and finding that you've lost nine months of your life - it is scary.'
