Married At First Sight star Domenica Calarco has shared an update with her fans as she moves forward in her difficult pregnancy.

The 31-year-old posed for a photo with her growing bump on show and shared with her Instagram followers that she has reached 16 weeks.

’16 weeks with my little baby bear’ she wrote in the caption alongside the image.

She told her fans in a Q&A session on Instagram Stories that she’s made two trips to hospital due to thyroiditis.

‘Ended up in hospital twice over my first trimester for fluids and to monitor bub when my thyroiditis was at its peak!’ she wrote.

Dom also shared that she had lost six kilos since falling pregnant due to the illness and was ‘scared of being judged for that’.

‘I lost six kilos and feel like a shell of myself right now, so trying to put on weight and eat as much as I can while I still don’t really have an appetite. It’s a journey’ she said.

Thyroiditis is a condition causing thyroid gland inflammation, often caused by the autoimmune disease Hashimoto’s.

Dom recently confirmed she will be a solo parent, days after announcing her pregnancy.

The former reality TV star sparked concern that she had split from her boyfriend Jarod Bogunovich, by deleting all trace of the Bondi skater from her social media.

Domenica exclusively confirmed to Daily Mail Australia that she will be raising her child as a single mum, as she addressed the break up rumours.

‘I am incredibly excited about this next chapter in my life and feel truly empowered by my decision to step into motherhood on my own terms,’ she said.

‘While I will be welcoming this baby as a solo parent, I am grateful to have the support of the father in a co-parenting capacity.’

Domenica, who rose to fame in 2022 on season nine of the hit series, said she is embracing this journey ‘wholeheartedly’.

‘Been a little MIA working on my greatest project yet…..Baby,’ the MAFS alum captioned her pregnancy announcement post on Thursday.

She added: ‘Due September 2025 #pregnancyannouncement #pregnant.’

Domenica’s followers noticed there was no sign or mention of Jarod in the announcement, and took to the comment section to ask if everything was all right.

‘Congratulations. I can only assume since there is no talk of a partner that you have decided to do this alone and as a single mum by choice,’ one person wrote and a second asked: ‘Where’s the father?’

Domenica is asking her fans to respect her privacy, as she explains that she is ‘proud’ that she has made ‘the best decision’ for herself, and her unborn child.

‘This journey is one that I embrace wholeheartedly, with all its highs and lows, and I am beyond proud to be stepping into this role [as a single mum] with strength, love, and a deep sense of purpose,’ she said.

‘I also want to acknowledge and support others who choose to embark on parenthood alone — there is so much power in making the best decision for yourself and your child.’

The brunette bombshell recently commented on a TikTok by influencer Sasha Morpeth, who was discussing a painful breakup. ‘Join the club, argh,’ she wrote.

The pair had gone Instagram Official in September, after rekindling their romance after Domenica’s MAFS marriage to Jack Millar crumbled.

Domenica and Jarod met on Bumble in 2021, and she went on a date with him before she was cast on Australia’s ratings bonanza television show.

The timing wasn’t quite right, she later revealed, and they went their separate ways.

Years later, they bumped into one another at a boxing gym Pad Flow in Sydney, and reconnected.

In her Instagram Stories, Dom revealed she was 14 weeks pregnant. Jarod was absent from the post.

As recently as last October, Domenica told Daily Mail Australia ‘the universe brought me a good one,’ as she detailed their romance.

‘Jarod has the best smile in the world,’ she said. ‘Whenever he smiles at me, I melt.’

‘It feels amazing to have met someone at this time in my life after going through a very difficult period.’

‘Jarrod stuck by me,’ she continued, referring to the period of time she spent in hospital working on her mental health after a very pubic friendship break up with her podcast host Ella Ding.

‘He didn’t run away. We actually got closer during that time,’ she confessed.

Domenica said she will not be commenting further on her relationship status during her pregnancy.

‘At this time, I have nothing more to say on the matter and appreciate the respect of my privacy as I prepare for this exciting new chapter,’ she concluded.
