Menstrual cramps are pains in a woman's lower abdomen that occur when her menstrual period begins (or just before) and may continue for two to three days. They may be throbbing or aching and can be dull or sharp. Symptoms can range in severity from a mild annoyance to severe pain that interferes with normal activities. Menstrual cramps are the leading cause of absenteeism in women younger than 30. Although over half of women who have menstrual periods experience some discomfort, 10% are temporarily disabled by symptoms.
On January 1, 1901, a federation of colonies took shape after years of discussions and planning. The Commonwealth of Australia was created as a Dominion of the British Empire, and a new nation was born. Western Australia, granted self-government in 1889 by the British, was the most reluctant participant in this new Commonwealth of Australia, but joined nevertheless.
Separate settlements and later, colonies, were created from parts of New South Wales: South Australia in 1836, New Zealand in 1840, Port Phillip District in 1834, later becoming the colony of Victoria in 1851, and Queensland in 1859. The Northern Territory was founded in 1863 as part of South Australia.ew South Wales in 1855 was the first colony to gain responsible government, managing most of its own affairs while remaining part of the British Empire. Victoria, Tasmania, and South Australia followed in 1856; Queensland, from its foundation in 1859; and Western Australia, in 1890.
