The months and years that followed were definitely not easy for the now 24-year-old, but Catie has never regretted her decision.
“I had no idea I was pregnant until my sister called me one day and said ‘You’re pregnant'”, she told Mamamia. “I thought it was a really weird thing to say to someone, but she was right.”
“Of course my life changed forever from that day, but for me there was never a decision to make,” she said. “I just had this intense feeling that I had to have this baby.”
Looking back, Catie can now recognise some of the signs of pregnancy from those early days - for one, she was suddenly turned off by chicken noodles and the 16-year-old always loved chicken noodles.
"I couldn't eat one of my favourite foods in the world and I had missed a period, but I just hadn't put it all together."
Catie was petrified of telling her parents, but their reactions helped cement her decision.
"I told my dad on the phone and he congratulated me," she recalled. "He said he was a bit disappointed in me and that this wasn't what he wanted for me, but he congratulated me and said he would be there to support me."
