As previously reported, the 26-year-old opened up about overcoming her cancer three years ago with the father of her baby Nate Myles, by her side.
'For Nate and me, it was our first real challenge as a couple and it was hard and not nice, and not glamorous and very confronting,' recalled Tessa.
'But at the same time, life's not going to be perfect and we are so much better because of it.'
Continuing on, the stunner revealed she wasn't a fan of people calling her ability to bare a child "a miracle'.
'I think that 'miracle' has come from the media and not from something that I've said, but in saying that, being pregnant is a miracle because growing a baby, it's pretty incredible when you think about it,' she said.
The former Home And Away actress is due to give birth at the end of the year.
Myles, 32, and the expectant mother have been married since 2011.
