I volunteered for awhile as a P.A.S.S (Post Abortion Stress Syndrome) counselor at our local pregnancy resource center because there was such a need for this demographic of women. The abortion clinics couldn't offer this service without acknowledging the liability, so they could offer only referrals, some sliding scale - but none free.
What I noted with interest during my time doing that counseling is how few women I saw who had just had abortions. I think there is a certain period of denial. There were a few who were within a month or two of their abortion, but most were a year or more, sometimes many years, after the fact of their abortion and were just now coming to terms with it.
This is one reason why I am thankful when I see women considering abortion being encouraged to not to react hastily to the fear we all have when something unplanned and seemingly daunting comes to us. Abortion is so huge, so much more than merely 'removing a pregnancy.'
And as you note, there is a huge portion of that that is concern for women. We have instincts! And we don't do well when pressured either from within or without to overrule them.
