(i normally post on the pro-life board but I hope I can be allowed to make this post here. I will delete it if its presence irritates anyone.)
.Carifairy, I sympathise with your predicament. Due to your 'inside knowledge', the unenviable task has fallen to you to be the advisor in these situations and that's a heavy burden to bear.
I think you have been doing the right thing though. These women are going to abort anyway and you have potentially saved their lives by informing them of how to do the procedure as safely as possible. As much as i'd rather the women weren't going to abort their babies, I would rather just the one life be lost than both the mother
and child to die.
I don't know where you stand legally by giving out such information, though. I hope you are not risking yourself in any way.
