After her followers expressed concern about her absence from social media, Charlotte said that she had experienced baby loss and only her friends and family had known she was expecting.
In a post shared on Monday afternoon, Charlotte wrote: "Hi my darlings, I finally feel ready to post this.. I mean I don’t know when there is a good time to post this.
"It’s been an extremely tough week mentally but also obviously physically… I am heartbroken beyond words.. and I know I’m never quiet on here, & always so open and honest with you guys so it’s been a shock to you all.."
Noah was rushed to the hospital last week after he banged his head and cheek on a table leg and passed out. He was eventually given the all clear to return home later.
"I keep getting lots & lots of messages worrying about us all, asking why I’m being quiet & if Noah is ok.. Noah is absolutely fine.. he’s amazing. I’m the one that’s not ok.. unfortunately I’ve suffered with a miscarriage.
"Obviously our families & close friends have known about me being pregnant, but didn’t announce anything until I got further down the line.."
The 29-year-old is mum to son Noah, one, and she spoke on behalf of her partner Matthew Sarsfield about their loss.
She also shared a video of herself holding a pregnancy test and telling her young son that he's "gonna have a little brother or sister". The reality TV star shared in the caption that she discovered she was pregnant on Mother's Day last month.
"I was so excited to share our happy news with you all. Noah’s little brother or little sister, as you can imagine Matthew & I were absolutely over the moon our little family was going to be growing. I also found out on mother’s day which was just so special.
"But sometimes it’s just not meant to be, I really thought it was but it just wasn’t this time. Miscarriages are so common & not spoke about enough. We are so heartbroken right now have no words and just don’t feel Upto posting being my happy silly self right now.."
Charlotte also asked her followers to refrain from sending her or her partner 'nasty' messages during their time of grief. She said: "Also please can people stop sending Matthew & I nasty messages about our parenting skills. I clearly show and say far too much, we are bloody good parents and Noah is so loved and is our life.
"And these horrible forums talking about us, these trolls are just awful but they won’t win.. any nasty vile comments I get on here about this you will be getting blocked and reported.
"Thank you for all your love & support always, I don’t ever want to let go of Noah.. I feel so lucky to have Noah, one day we will get our rainbow baby.."
