A MELBOURNE woman thought she was growing a “food baby” during her dream European adventure.

But Kate Hudson, 22, was pregnant.

And within days, the media student went from seeing the sights of Prague to giving birth at the Royal Women’s Hospital back home in Melbourne.

“I had absolutely no clear symptoms. I was still getting regular periods,” Ms Hudson said.

“I wasn’t nauseous, no morning sickness, little weight gain, so it seemed silly to think I would be pregnant.”

Ms Hudson toldThe Young Mummy she didn’t even have a bump.

“Any belly I had I thought was just a food baby from all the eating I’d done in Europe over two months,” she said.

Seven weeks after leaving her boyfriend, she felt strange in the beachside Spanish city of San Sebastian, and took a pregnancy test that turned out to be positive.

She continued travelling, thinking the pregnancy was new, but then an obstetrician in Prague told her she was 33 weeks along.

“I was scared because I didn’t know if the baby was healthy,” Ms Hudson said.

“Obviously having not known for so long, I was exercising heaps, jumping off cliffs, riding bikes, drinking alcohol and eating anything and everything.”

She quickly boarded a flight for Melbourne in late August and “basically cried for the 22 hours”, while she felt her baby kick for the first time.

But there was another surprise when she got home — Ms Hudson was actually 38 weeks along.

“People just couldn’t believe it. I would tell them the story, then they would understand, but still it’s a pretty unbelievable story especially for someone my size,” she told The Young Mummy.

Within days, she had given birth to her son Mason.

Doctors told her she had a tilted uterus, which meant the pregnancy was not obvious.

“It’s hard to get my head around it, even now he’s eight weeks old,” Ms Hudson said.

“I wake up in the morning and sometimes forget that I have a baby. It’s a huge change and very overwhelming. I didn’t have the eight or so months to prepare.”

“I honestly don’t know if I’m doing it right or wrong. But he’s a happy baby and gaining weight, so I must be doing something right.”

“I have a beautiful healthy baby boy ... So I can’t complain too much. I’ve just gotta roll with it and make the most of it.”
