Jo Bennett, of Dawley Bank, went to A&E at Telford's Princess Royal Hospital with her husband Richard last month, but was told her uncomfortable feeling was actually contractions and she was in labour.
Hours later – on April 2 – she gave birth to a healthy baby boy, Jacob, weighing in at 9lb.
Richard says the couple's lives have been 'flipped upside down' by the 'amazing' surprise arrival and has thanked the midwives at Shrewsbury and Telford Hospital NHS Trust for the care they provided.
He said: “My wife, Jo, and I were busy playing along our usual Thursday night online quiz when Jo started getting stomach pains which got progressively worse.
"After a couple of hours, and with Jo now in constant pain, we attended A&E.
"A short time later we were told that the stomach pains were in fact contractions and that Jo was in labour.
"Sixteen hours later she gave birth to our son, Jacob at a weight of 9lb.
“Our world has been flipped upside down. We didn’t have a clue we were expecting and this is our first child.
"It has been a massive, but amazing, shock to the system and indeed to our entire lives."
He said throughout their time in hospital, the staff were 'amazing'.
"Sarah, the healthcare assistant in A&E, stayed with Jo until I got there and remained with us until we were transferred to the delivery suite," he added.
"She was truly wonderful, so caring and had all the time in the world to help us."
The couple have shared their experience as the world marks International Day of the Midwife, which acknowledges the critical role midwives fulfil.
“On International Day of the Midwife, we also want to say a massive thank you to the two midwives who helped to bring Jacob into the world," Richard said.
"Olivia, who was with us for the first few hours of Jo’s labour, was so comforting and relaxing and she returned the following evening to look after us for another 12 hour shift.
"Zen, who was with us when Jacob was born, was at our side every step of the way.
"Whatever we needed she went above and beyond to sort it.
"She explained everything that was going on and answered every question we had, which was a lot seeing as we have no idea about pregnancy or having a baby.
“Please, the next time you see an NHS worker, buy them a drink, or at the very least just thank them for all they do.
"To every midwife and NHS worker out there, thank you from the bottom of our hearts for all that you do."
Hayley Flavell, director of nursing at SaTH, which also runs Royal Shrewsbury Hospital, said: “On behalf of the trust I would like to say congratulations to Richard and Jo on the safe arrival of their son, Jacob.
“Giving birth is a life-changing moment for any parent, but never more-so than when facing a global pandemic.
"Throughout this time of great uncertainty, our midwives have provided compassionate and invaluable care.
"Thank you to each and every one of them."
