I disagree. From what I've heard, six weeks is rather tight timing and many women don't even know they might be pregnant until most of that is already used up! Think about it, your first indication is probably being late for your period and that is already four weeks--- or more if you think you are just running late. That leaves almost no time to get the abortion. I would have been happier with something in the 10-16 week time frame. And that leaves time to get a little counseling to maybe be convinced to keep the child.
Likewise with the rape. Great that they have the necessary exemptions, but if rape et al is an exception, why impose the stupid 45 day time limit? These are very troubling times for a woman, she has been profoundly violated, and it may take longer than that for her to even come around to even being willing to report it. All this does is make it even harder for a person who is literally suffering shock, horror and shame.
