A clerical assistant received an unexpected surprise when she collapsed with stomach pains and gave birth to a healthy daughter.
Mrs Mackinder gave birth after collapsing with stomach pains
Caroline Mackinder, 36, of Thorngumbald, is no stranger to unexpected pregnancies -it is the second time it has happened.
Three years ago she went to hospital with suspected appendicitis and walked out with her first daughter, Julie.
"It took me a week to get over the shock," said Mrs Mackinder.
She and husband Peter, 46, have named their newborn Nicola after ambulance crew member Nick Gee who helped to deliver the 9lb 2oz baby.
"As soon as I started with the shooting pain I presumed I was in labour because exactly the same thing happened with Julie, and within an hour on both occasions I had given birth," said Mrs Mackinder.
"I had put a bit of weight on, but I was still having my periods so I had no idea I was pregnant."
Caroline then had some explaining to do when she called her manager at the JobCentre in Hull and asked for maternity leave.
"When I explained I had given birth over the weekend he couldn't believe it, and said he needed to sit down. I said, 'just think how I felt'."
