Constance Hall is pregnant with her 5th baby: 'We have no idea how it slipped through'.

Perth blogger Constance Hall has announced she’s pregnant with her fifth child in a typically candid Facebook post.

The mum-of-six told her followers she and her fiance Denim Cooke have “no idea” how a baby “slipped through” before listing contraceptive methods the couple tried.

“We tried everything, on and off bouts of the pill… withdrawal, morning after pills. We actually have no idea how this baby slipped through.”

“But it did.”

The 33-year-old said she estimates she is about eight weeks pregnant and is due in June, but hasn’t had this formally confirmed by a doctor yet.

While the pregnancy wasn’t planned, Hall says she and Cooke are happy. She met father-of-two Cooke in February and after ending her marriage with ex-husband and father of her four children, Bill Mahon.

“We are not ready for this and I am petrified, babies terrify me. But are we happy? Pigs in shit.”

“Well…. I’m hormonal, I considered having an abortion this morning because Densy slept in.

“However I love this mother fucker, with every inch of my bloated body, we are our kids biggest fans and we don’t see the harm in putting a new little soul right in the middle of it all.”

Hall concluded by telling her followers to expect to hear complaining from her.

Congratulations to the entire Hall/Cooke clan!
