Hall already shares four children with ex-partner Bill Mahon, and Cooke is a father of two.
Within minutes of announcing her pregnancy the Perth bloggers social media pages were inundated with negative comments.
The 33-year-old announced the couples happy announcement by captioning a photo, 'We are not ready for this and I am petrified, babies terrify me.'
It continued, 'But are we happy? Pigs in s***. Well…. I’m hormonal, I considered having an abortion this morning because Densy slept in.'
Hall has now responded to the criticism.
'A lot of people are angry that I joked about abortion,' she began her post. 'Actually, I was dead set serious.'
The mum-of-six said she did consider an abortion and she actually called her sister to talk about it.
'I am pro choice, I always have been and I believe in normalising abortions, they shouldn’t be a dirty secret that we don’t discuss in public forums.
'That said, I consider abortions and miscarriage/fertility issues two very separate topics. And I would never joke about the latter.'
Hall finished up her post by apologising to those who had been offended by her comments.
'So I am sorry for offending those that were offended. It wasn’t intended to offend.'
