A woman who had no idea that she was pregnant gave birth in the toilet of a hotel, on the same day that a pregnancy test came back negative.
New mum Stacey, 25, had been suffering back pains while visiting a Harry Potter convention in Manchester city centre.
She'd told doctors that she hadn't been feeling well, but a pregnancy test showed she wasn't carrying a baby.
Her story is told on the BBC series Ambulance, Manchester Evening News reports .
The BAFTA award-winning series has returned to follow the work of staff from North West Ambulance Service in and around Greater Manchester.
Stacey's worried friend called for an ambulance explaining: "My friend, she's not been well all day and then she's literally just had a baby."
With an ambulance on the way to the Brittania Hotel in Portland Street, the call handler gave her friend advice over the phone.
"Make sure the cord is not wrapped around the baby's neck. Watch the baby closely for three minutes then tie the cord with a string or shoelace," she told her.
"Tie the string tightly around the umbilical cord about six inches from the baby, but do not cut it."
Paramedic Jon arrived at the hotel to find the patient in the bathroom clutching her newborn baby and the new mother explained she had no idea she was pregnant - she had even been to the doctor that morning.
She explained: "I've had like, really bad back pain. The next thing I know I'm pushing and then I can feel like a head on me.
"I've been at the doctor's today cos I have got like a bump but they've said 'so the pregnancy test said no, negative.' So they were like 'we'll test you to see if you've got a cyst or anything.'"
Asked if her daughter had cried straight away she replied: "No, she was in the toilet and I had to pull her out.
"I put her into the sink and then she started trying to cry and then she cried."
Jon cut the cord in the hotel room and as he continued to treat both the mum and her baby, who he suggested she should name after Harry Potter character Hermoine Granger.
But he was concerned that Stacey had a potentially life-threatening blood clot.
In the ambulance en-route to St Mary's Hospital Stacey told Jon that she was naming her daughter Elizabeth.
From the hospital Jon reported back to the call centre that she had a postpartum haemorrhage, excessive bleeding following the birth of a baby, and her boyfriend had been told and was on his way over from Leeds to see Stacey and baby.
At the end of the programme it was explained that had Stacey made a full recovery.
