She revealed that she has been in and out of hospital overnight stays and being monitored due to an “irritable uterus”, and that it has been “painful and arduous”.
“This is how we hang for now - I know he will come at the perfect time so I’m just going to try and enjoy the last days of pregnancy while navigating the pain and exhaustion.”
She added: “Bed rest and staying positive with an amazing supportive hubby.”
The current mum-of-one is expecting to welcome her second child, a baby boy with husband Nathan Constable, over the coming weeks.
The 38-year-old married her long time love Nathan not too long ago, after the pair hosted a surprise baby shower turned wedding celebration.
"We're married!!!! Mr + Mrs Constable! Forever my always... So this was our big surprise!! A baby shower turned wedding celebration!" Tracey wrote alongside a picture of the two from the special day.
The couple are ready to expand their little family, with Tracey already a mum to 10-year-old daughter Grace from a previous relationship.
She’s due to give birth to her second child very soon, and first announced her pregnancy in true form on Instagram.
"We're having a baby! We are so happy to share our beautiful news with everyone," Tracey wrote alongside a photo of herself and Nate, plus an ultrasound snap.
"I have always believed in second chances and my second baby I've been waiting so long for..." she added.
