An Australian woman, who didn't know she was pregnant, was shocked to give birth to a healthy baby on May 1 after she was rushed to the hospital after complaining of stomach pains. Sarah Currin, 25, has moved to the UK since 2012 from Brisbane, Australia.

In a report by the Daily Mail, Ms Currin said she woke up in the morning and felt "a little bit off" but she decided to go to work anyway. She said she felt pain around 11 in the morning, but she still tried to work.

However, a few hours later, she called an ambulance because she thought she was having severe stomach cramps. She was rushed to the hospital for what she suspected was appendicitis. Her doctor also thought she had a stomach bug.

It wasn't until the midwives began checking her stomach that they told her she had to "push." Ms Currin felt completely clueless and scared at the same time because she didn't know what was happening.

According to Dr Paul Bretz from Arrivals Obstetricians at Woolloongabba, although the situation was rare, it was not unheard of. She said she has seen three or four cases in her more than 20 years of practice.

Bretz said she was aware of cases when women tend to misinterpret the symptoms of pregnancy. In one case, a woman in her 40s who attributed her lack of periods to menopause. Another woman didn't think she was pregnant because she thought her breastfeeding caused her lack of periods.

The doctor said women who are not expecting pregnancy will read the signs wrong and often blame them for something else.

According to Currin, she didn't notice anything odd about her body. She said she gained weight slightly. She couldn't believe she was unaware she had a baby inside her all that time.

Now, she and her partner James are happy about the arrival of their baby named Brooke.

The weight of the baby was 2.7 kilogrammes when she was born. Bretz said it was normal but the weight was on the lower end of the normal range. She believes this was the reason why the baby was "more easily hidden."
