I have a hard line of no post-first trimester (up to 12 weeks) abortions outside of some sort of serious defect or the pregnancy being life threatening. My own line would be 9 weeks, but I'm not sure that I could go through the process myself. I certainly don't consider them to be anymore than the framework of basic human anatomy til after maybe 9 weeks. They don't have complex enough brain/nervous system development that early on to even feel pain.
