A Cairns couple will face trial on charges of procuring a miscarriage.

Late last year, 19-year-old Tegan Simone Leach found she was pregnant.

Ms Leach and her boyfriend, Sergie Brennan, 21, consulted their mothers and, on the advice of their families, the couple decided it was best to end the pregnancy.

But rather than have an abortion in a public hospital or private clinic, it was decided Ms Leach should take the abortion drugs Misoprostol and RU486 at home.

Ms Leach has been charged with procuring her own miscarriage.
