Baby ain't cheap, tests are :)
For less than a price of lollipops, you can get a pregnancy test kit. This is fraction of the cost of normal kit from chemist/supermarket and from the user review's, it seems quite a decent kit for 30c :p
It's great complement if you buy their 50 pack condoms (http://www.ozbargain.com.au/node/7840), consider it as 'insurance'.
Description from the site (it's rather amusing :D):
- Tests for early pregnancy
- Shows results in as little as 60 seconds
- Cheap disposable solution to have for all families
- Each test paper individually sealed in a convenient thin pack
Ha, you're asking for trouble yet again! :)
