The Save the 8th Campaign say the government's plans would allow abortion for healthy babies up to 6 months into pregnancy.
The proposed legislation allows for terminations before viability if there's a serious risk to the health or life of the mother.
Two doctors including one obstetrician or gynaecologist would have to examine the woman and approve an abortion in cases where a termination was sought after 12 weeks into pregnancy.
Save the 8th spokesperson Mairead Hughes says the 8th amendment protected her during her own pregnancy.
