A Scottish teenager has told how she unexpectedly gave birth after having no idea she was even pregnant.
Siobhan Buchanan, now 19, from Perth, said she was practicing safe sex with her then-boyfriend, Kieran Millar, now 21.
The mum, who was also a petite size six, never had a bump and said her periods didn't stop during the pregnancy, reports the Daily Record.
Siobhan was rushed to hospital in March 2019, after experiencing excruciating back pains at work the day before.
Shocked Siobhan, says: "I'd been using condoms with my boyfriend, had a flat stomach and had periods every month.
"I couldn't believe I'd carried a baby for nine months without knowing.
"Thankfully, he was a healthy little boy."
The stay-at-home mum was just 17 and a slim size six when she fell pregnant without even knowing it.
Looking back, she can remember that her face had become suddenly spotty and Siobhan's mum, Yvonne Buchanan a shop assistant, noticed she looked 'puffy'.
Siobhan said: "Mum kept saying my face was swollen and fat.
"As I'd also broken out in pimples, which wasn't like me, she became convinced I was pregnant.
"I laughed and told her not to be ridiculous. Kieran and I used condoms and were extremely careful.
"Plus, my periods were regular so it was impossible."
Siobhan's mum wouldn't let it go and in January 2019, she convinced Siobhan to take a pregnancy test.
Siobhan says: "Like I thought, it was negative.
"Mum was shocked and kept saying I looked like I had glowing pregnancy skin, I told her to drop it.
"Soon after, I started to crave bagels and Irn-Bru.
"I looked at my stomach and it was completely flat, I knew I wasn't pregnant.
"Mum was still adamant and she bought me two different brands of pregnancy tests again
"To keep her quiet, I took them and again, they were negative."
But two months later Siobhan experienced agonising lower back pain while she was at work.
She explained: "Out of nowhere, I had horrible pain in my back. I thought it was my uncomfortable chair.
"Later that night, at home, I kept complaining to my parents that my back was killing.
"Mum gave me some ibuprofen. Dad thought I might be constipated.
"I decided to just get an early night and sleep it off."
But the next day the pain got worse and Siobhan was rushed to Perth Royal Infirmary hospital after water gushed from her legs.
She says: "I dragged myself to the toilet and as I sat down, I felt a gush of water between my legs, I was so confused.
"Mum and Dad were out so I called them and told them something was wrong and that I needed to go to the hospital."
At the hospital, a doctor demanded she took a pregnancy test, Siobhan said: "I was fed up of taking them. I knew it'd be negative, but I had no choice.
"A few minutes after, I was told I needed to be taken to another hospital.
"They wheeled me into an ambulance and I had no idea what was going on.
"Mum jumped in with me while Dad went back to work."
She was then taken to Ninewells Hospital, Dundee where she found out she was about to give birth.
She says: "To my shock, they took me to a maternity ward and did an ultrasound.
"Suddenly, I heard the thumping sound of a heartbeat.
"I looked at the screen and there was a baby. I was in labour.
"Before I could react, I felt burning between my legs and the nurses told me I was crowning."
Just ten minutes later, Siobhan gave birth to a baby son, who weighed 5lb 5oz and despite not knowing she was pregnant the baby was given a clean bill of health.
Siobhan says: "I stared at my son in disbelief.
"Mum was crying and cradled him. The doctor explained that he'd been lying back to back, which is why I didn't have a bump.
"For months, I'd mistaken spotting for light periods.
"As Mum quickly called Dad to tell him the news, I messaged Kieran.
"I said I'd had a baby and he was a dad, he thought I was joking but then it finally sunk in. He was gobsmacked.
"Sadly he was stuck at work, so he couldn't come straight away."
Two hours later, Siobhan's dad rushed to the hospital to see her and Siobhan named her son Oscar. Her baby boy is now 23 months old and he and Siobhan have their own home.
Siobhan says: "I can't wait to tell Oscar the story about his birth when he's older.
"He surprised us all. Now, my mum constantly gets to say 'I told you so!'
Siobhan says: "After five days, I took Oscar home and Kieran finally met him.
