Women in Ireland are tweeting stories of their menstrual cycles to Irish Prime Minister Enda Kenny as part of a campaign to repeal the country’s strict laws banning abortion.

The Guardian reports that the campaign #repealthe8th aims to overturn the eight amendment to the country’s constitution, which criminalizes abortion.

Anyone who procures an abortion illegally can be punished with a 14-year prison sentence. Abortion is only legal in Ireland if the woman’s life is determined to be at risk.

Grainne Maguire, the woman behind the campaign, has encouraged Irish women to share the details of their periods:

“Women of Ireland! Your vagina is their business! Tweet @EndaKennyTD your menstrual cycle #repealthe8th”

Many women have followed Maguire’s lead:

Kenny has not responded on Twitter, but the taoiseach has said he will not commit his Fine Gael party to a referendum on the issue.

“In respect of the eighth amendment I do not favour abortion on demand and I have no intention of abolishing the eighth amendment without considering what it might be that might replace it,” said Kenny.

“But believe me, believe me, to commit to abolishing the eighth amendment without consideration of what you might do is not on my radar.”

Ireland’s abortion ban has become a major issue in the run-up to the country’s next general election.

67 percent of Irish would like to see abortion decriminalized according to Amnesty International’s newest study.iStock
