Betty: that's kind of what I use as a guideline. Obviously it's very difficult to define a line between when it's a part of the mother's body that she gets to have dominion over and when it must be considered an individual being that gets to impose itself on the mother a little longer.

A fertilized egg cannot survive out of the womb. A nearly full-term baby can. Where the line falls in the middle, tough to say. So I tend to think that when the baby could theoretically be delivered that day and survive, then it's too late to abort. That's somewhere around the 5.5-6 month mark, I believe. I think that's more than enough time to decide whether or not you're keeping it.
