“I’m really getting so much bigger and I can feel the stretch,” she said of her baby bump.

Martha, who is now 31 weeks pregnant, then promoted an oil product that she has been using while her belly continues to grow.

It comes after Martha revealed she didn’t have sex during her pregnancy.

Martha (pictured with fiancé Michael Brunelli) revealed she was in her third trimester earlier this month and admitted her pregnancy journey had been both “exciting and terrifying”.

She told the Kyle and Jackie O Show that she was staying at her mother’s home in Melbourne after suffering from severe hyperemesis gravidarum – a condition that causes prolonged and excessive vomiting during pregnancy.

“So you and Michael are having sex in your mother’s bed?” Kyle asked Sandilands.

Martha tried to end the question by asking Kyle how many times he had sex with his fiancee Tegan Kynaston while she was pregnant with their son Otto.

He admitted “once or twice”.

“We haven’t had our once or twice moment yet, but who knows? It is [Michael’s] birthday [soon],’ She said.

Martha and her fiancé, Michael Brunelli, are expecting their first child together, but it hasn’t been an easy pregnancy journey for the couple.

Michael recently revealed how Martha’s morning sickness “almost destroyed” their relationship.

In an article for Body & Soul, the 31-year-old personal trainer said grooming Martha has caused him to abandon healthy habits, lose muscle and gain weight.

“Not to say we aren’t eternally grateful to be able to conceive, but the experience almost devastated us personally,” he wrote, before explaining that Martha’s health was declining rapidly after becoming pregnant earlier this year .

Michael explained that at first he thought her symptoms were normal, but over the weeks her discomfort had become “extreme”.

“She was vomiting, refusing to eat, intolerant of water, nauseous 24 hours a day and unable to get out of bed,” he added.

Michael stopped working as a personal trainer to take care of his wife-to-be – but also saw his mental and physical health deteriorate.

“I stopped exercising, lost attention to what I was eating, I was stuck in my own head and not present. I had zero motivation, zero willpower, zero self-care, and zero energy. I lost a lot of muscle mass, gained weight, slept poorly and my overall health deteriorated,” he added.

Fortunately, after 22 weeks, Martha’s illness subsided and she is now able to return to her daily activities and Michael is back at work.

What is hyperemesis gravidarum?

Hyperemesis gravidarum (HG) is a condition that causes prolonged and excessive vomiting during pregnancy.

Sufferers may be sick many times each day and unable to keep food or water down, affecting their daily lives.

It is unlikely to harm the baby, but if it causes a woman to lose weight during pregnancy, there is an increased risk that her baby will be low birth weight.

It differs from nausea during pregnancy – often referred to as morning sickness – which is normal and affects eight out of ten pregnant women. For most, this stops or improves around weeks 16 to 20.

Meanwhile, HG may not get better at this point and may continue until the baby is born.

Symptoms of HG include persistent and severe nausea and vomiting, dehydration, weight loss, and low blood pressure.

Dehydration increases the risk of a blood clot – deep vein thrombosis – but this is rare.

It’s not clear what causes the condition or why some women get it and others don’t.

Some experts believe this could be related to changing hormones in the body during pregnancy.

And there is some evidence that it runs in families and women who have suffered it during their first pregnancy are more likely to have it in all subsequent pregnancies.

Women suffering from HG may be given medications to improve their symptoms, such as anti-nausea medication, vitamins B6 and B12, and steroids.

Some women need to be hospitalized if their nausea cannot be controlled with home medication.

You may need fluids and anti-nausea medication, which will need to be given via an IV.
