A teenager who kept having her periods and fitting into her size six clothes was shocked when she discovered she was pregnant during labour.
Ellisha Ford, 17, had no idea she'd been expecting as her tummy had stayed flat throughout the nine months, while she kept going out on plenty of walks without any issue.
The college student also took pregnancy tests, including on the very same morning she gave birth, but they always came back negative.
The only sign was in March, when she had blood tests and a pregnancy test - which came back negative - because of a back ache.
The doctor said it was most likely the pain was down to sciatica or her overactive thyroid.

It was only at 43 weeks that she went in to see a doctor for a stomach pain that the incredible truth was unearthed.
Ellisha, from Coalville, Leicestershire, recollected how the doctor felt her stomach and it turned out she'd had a contraction.
She was given an ultrasound and it was only then that they realised she was in active labour, with a dilation of 6cm.
Little baby Harper was born hours later, happy and healthy, and mum and son bonded well despite his surprise arrival.
Ellisha said: "As soon as the doctor put pressure on my stomach my belly just came out - it was all really strange.
"And then they checked and I was 6cm dilated and told me I was going to have Harper that night.
"So I ended up having him five hours after I found out I was pregnant. My weight never changed throughout at all and I was still fitting into my size 6 and 8 clothes."
The teen continued with her life as normal, until three weeks before her birth, when she went to a walk in clinic - on what would have been her due date.
Again she had back pain, but was told it was down to sciatica again.
"Three weeks later I woke up in the morning with a really bad stomach ache and went to the hospital and they did a normal pregnancy test and told me I wasn't," she said.
"A doctor did feel my stomach as I had a contraction and he told me that I was definitely pregnant but thought I was not too far gone and said I was probably just having a miscarriage.
"They then did a scan and couldn't find him on the scan but then another doctor flipped the screen around and he saw and he just said I was actually full term.
"That was when I was in the delivery suite and it was just all really strange.
"My mum told me that she had had my brother when she was quite young and she just came into the room and said there was nothing we could do I would just have to get the baby out and stay as calm as I could."
Baby Harper was born at 43 weeks weighing 7lb 6.5oz at Leicester Royal Infirmary on August 2, 2020.
"When he was born he wasn't making any noise because he had swallowed lots of liquid so they took him off for ages," she said.
"When they gave him back to me I was like wow he's mine. It was just really strange and I didn't know what to think of it.
"My dad just thought he was gorgeous and just cried when he saw him."
She said the incredible twist of events made it "easier" for her as "I didn't have the nine months to get myself wound up over things.
"It was a case of I've got this baby and I've got to look after him.
"We did tell his father as well but I was petrified of telling him and when my mum showed him a picture and he just cried.
"I did end up being in hospital for five days afterwards as I had really bad preeclampsia but Harper was perfectly fine and perfectly healthy.
"I know this does happen to a lot of people and I will sometimes sit there and be like I'm so stupid for not knowing but it does happen people."
