Annie Tupou found out she was pregnant at six months, which came as a shock to begin with.
But a week and a half after finding out she was having her ninth child, she went into labour and gave birth to twin girls.
“I never got dizzy or anything else … I sometimes got tired like really drained out sort of thing but belly wise I wasn’t showing that much,” Ms Tupou told 9News.
Ms Tupou from McCrae on the Mornington Peninsula shared her story on a Facebook mother’s group.
“I had recently posted last week about tying my tubes after baby number nine as I literally found out a week and a half ago I was pregnant, and I was finding out this Thursday what I was having at my ultrasound,” she wrote.
“Well I never made it to my ultrasound did I.”
The mother said she thought she was having Braxton Hicks contractions, but just after 3am on April 25 when she went to use the bathroom, her babies decided it was time to enter the world.
“I reached down and my baby girl’s head was half out!!!,” Ms Tupou said in her post.
“I got into midwife mode as my hubby was in Sydney for work, I got blankets and towels … and Twin A slid out straight away coming into this world at 3.45am.”
Three ambulances arrived and tended to the tiny child.
“I felt like I was in a movie,” she said.
At the hospital, the mother of nine at that point was in considerable pain she believed was caused by remaining placenta.
The midwife told Ms Tupou to push, but as soon as she started a nurse yelled “code blue”.
“All these midwives ran into the room and I was like what’s going on? And she said ‘that’s not a placenta that’s another BABY!,” Ms Tupou wrote.
The surprised mother said she was in such a state of shock her emotions were largely kept at bay.
“I was so shocked I just had another baby!!,” she posted.
“Twin B was born at 5.45am so my twin girls were born two hours apart.”
“It will be a long road to recovery but they’re here and now I have 10 kids under 10, five boys and five girls – my family is complete,” Ms Tupou said.
The super mum said she wanted to thank the paramedics who helped her during her labour.
“These two gentlemen were my backbone and never left until Twin B was born, I’m so thankful to them.”
Ms Tupou is hoping she can find out their names so she can send them a thank you gift “for loving their job and being dedicated.”
The twins, named Tilila and Leylani are expected to be in hospital for several months.
