Irish women are tweeting details of their periods to Prime Minister Enda Kenny to help publicize a campaign to repeal restrictive abortion laws.

Abortion is a divisive issue in Ireland where, after large street protests from both sides of the debate, a complete ban was only lifted in 2013 when terminations were allowed if a mother's life was in danger.

When Ireland chose to become the first country to adopt gay marriage in a referendum this year, marking a major shift in what was once a strongly Catholic and socially conservative society, calls for abortion law reform gained momentum.
