Home and Away star Sam Frost breaks her silence on why she quit the show

"I have to admit, the first trimester was incredibly difficult for me, mentally & physically," she said.

"I wasn't prepared for how taxing pregnancy would be on my mental health. Everyone tells you not to share your news until the 'safe zone' after 12 weeks - this is due to the risk of miscarriage dropping significantly after 12 weeks - Everyone is different, there's no one size fits all. If you feel more comfortable to wait, then please do.

"However, I told all my close girlfriends, gayfriends and family pretty much as soon as I tested positive on an at-home test. I was too excited to keep it a secret. I wanted to share the news with the people I love the most, and I am so glad I did, because once the symptoms kicked in (around 6 weeks) my mental health quickly deteriorated."

Frost, who also appeared on The Bachelorette in 2015, went on to say that she became bedridden for two months,"throwing up constantly with extreme exhaustion".

"I feel so far from the person I was. Before pregnancy I was fit, healthy, full of energy, keen for adventures, financially stable and always giggling my head off. Now, all I can stomach is Vegemite toast. I sleep literally the entire day, I only get up to wee (frequently) and throw up.

"I'm now at 15 weeks, while my nausea is slightly easing, I'm still not keeping things down."

The soap star added: "I cannot tell you how many times I have thought about all the women and families that aren't in the position where they can stay at home when they feel the same way. And for the single mama's doing it alone, I have nothing but absolute admiration and respect for you.

"This is not a pity piece. This is not written with the intention of wanting sympathy or attention. I wrote this because while I was going through the worst of it, I felt so alone. Social media glamourises pregnancy. No-one talks about the ugly truth."

Home and Away airs weekdays at 1.45pm on Channel 5 and 6pm on 5STAR. First-look screenings air at 6.30pm on 5STAR and the show also streams on My5.
