Married At First Sight UK star Jess O’Connor, known as Jess Potter, has welcomed her first child with her fiancé TJ O’Reilly.

The dental hygienist, who shot to fame on the E4 show in 2022, underwent four gruelling rounds of IVF before revealing earlier this year that she was expecting a baby.

Jess had previously suffered three miscarriages and a failed adoption and has been open about her battle with infertility.

Taking to Instagram on Wednesday, Jess shared the happy news that she and TJ has welcomed a baby girl called Mia Jane O’Reilly after 12 hours of labour and five days in hospital.

She shared an adorable picture of baby Mia along with snaps from her hospital bed after giving birth.

‘After 5 days at hospital, 4 days in early Labour, 12 hours of active labour… a lot of screaming. I had the birth I’ve always wanted…,’ she wrote. ‘Mia Jane OReilly 6lbs 6oz born 4:51am 23rd July. You’re perfect in every kind of way.’

Almost 24 hours before, Jess had shared a picture of herself in her hospital gown before going into active labour.

She captioned it: ‘Waters went 8am, on hormone drip, had epidural, only progressed 2cm in 12 hours, waiting for the doctor.’

Announcing her pregnancy in January, Jess shared a sweet video and wrote: ‘After almost 3 years, 3 failed IVF cycles, 4 losses, and hundreds of injections… Our journey has been filled with heartache, hope, and resilience. But today, we’re overwhelmed with gratitude to share with you:

‘Our miracle baby O’Reilly arriving July 2025! This little heartbeat is proof that dreams do come true, no matter how long the road may be.

‘Thank you to everyone who has supported us along the way. For anyone still waiting, we see you, and we’re holding space for your story. With love, Jess & Tom .’

Jess set up a GoFundMe page to raise £10k for the successful IVF round in February of last year.

She took to social media at the time to reveal she was planning to ask members of the public for help in funding her treatment after three failed rounds of IVF.

Days after revealing her attempt at adopting with her fiancé TJ O’Reilly had been rejected, she took to Instagram and TikTok to confirm they were seeking public funding after spending £15k on three rounds and losing three babies.

In a heartbreaking turn of events, Jess revealed she was receiving abuse from followers in the wake of her announcement, with some cruel critics branding her ‘a scrounger’ and claiming she should ‘save her own money’.

Despite criticism, she did however garner a whopping £1,825 of her £10k goal from 164 patrons, within 17 hours of going live, and continues to ask for cash from fans.

Jess, who became engaged to TJ in October, has been candid about her fertility journey, with her social media documenting her failed IVF bids.

Earlier this week, she revealed their attempts at adoption had failed as they have not been a couple long enough – leading to her GoFundMe attempt.

Taking to Instagram, she shared a selfie with her boyfriend and added a caption reading: ‘Right…we’re doing it!! GO FUND ME!! I know it’s A LOT to ask and of course we’re not expecting anything but we really do want one more shot at IVF…

‘We need further tests which (one test alone) costs £2000. Our embryos would need to be moved to another clinic which again is very costly. Then a new IVF protocol and hopefully [fingers crossed] a 4th (and final) transfer…

‘Praying that we get our happy ever after. All I’ve ever wanted is to be a mum and I just really want another shot at this!…

‘So if anyone can help in anyway I will be SO grateful!!!! – will keep everyone updated with everything as we go along of course ! Link is in bio if u are able to donate at all’.

On the GoFundMe page, Jess penned: ‘Hi, my names Jess and for the past 2 years me and my partner Tom have been trying for a baby. We have been unsuccessful…

‘We have had IVF three times resulting in 3 pregnancy losses. We would love to have another go at having a family, as being parents is all we have ever wanted but, we have spent over £15K and have no more savings…

‘IVF costs a ridiculous amount and after 3 losses we would have to do further investigations to try and find out why we cannot have a successful pregnancy which cost thousands alone…

‘Once we have discovered what could be causing all this heartache we would love to have another round of IVF…

‘We would need to move our embryos to another clinic that specialises in reoccurring pregnancy loss which again is very costly…

‘If anyone can help us in anyway to get near our goal of possibly having a child to love and complete us then we would be eternally grateful. x…

‘All i’ve ever wanted is to be a mum and this has been the hardest 2 years of my life. It’s drained the life out of me and the fact the money is causing another strain is heartbreaking. If anyone could help we would really appreciate it #IVFWARRIOR…

‘I will be posting regular updates on tests we will be having and results and hopefully we can start a new round of IVF before the summer. Thanks again <3'.
