most women who have the courage to seek medical care and treatment following a sex assault are quickly offered some version of prophylaxis-category of drugs to address the risks for hiv and a host of diseases. statistically, it's quite unusual for a woman to conceive under the trauma of rape, though they are almost always offered alternatives to prevent (or interrupt) this.
most women are offered some form of "plan b" - type drugs, and quite often, encouraged to get an IUD, all of which are designed to prevent either conception or implantation, which you have rather limited time windows for which to react. during the couple years i volunteered in this crisis care volunteer role, i never once saw a woman turn down at least one of the options intended prevent/eliminate pregnancy.
as a woman who has gone through her own traumatic sexual assualt, i have never felt any bit of judgment or obligation to discourage someone to do something she felt was best for her--only to make sure she understood exactly what she was taking or signing up for. and to make the decision for herself, and not because of what i think, or what she worries what others might think. you can't imagine how harrowing it is to see a young woman go through the horror of something as horrific as an assault and then shift all of her fear and worry towards what others will say, do, or think. how she will be judged. for a few years i would get ridiculously angry at folks who would judge and criticize choices of those facing such difficult circumstances.
in my own case, i had a reasonable hope i wouldn't get pregnant, but had i gotten pregnant, i'm not sure i would've done with myself. i doubt i'd have had an abortion, but i've never been pregnant or under the influence of all those consequences and time-limited scenarios.
i'd love to say i'd have been this force of courage and strength and done something admirable in spite of my situation. but sadly, i don't think anyone can really say what they would do until they are in that situation. sometimes i think there is plenty of courage in the lives of those who survive such things and choose to be bruised instead of broken by it all.
years ago i broke from the support group i was attending and quit serving as a crisis volunteer. i needed a break from all of it, and i saw women come there, and many left after awhile. but there were women who just never left that place of crisis, and it was obvious that 10 years or whatever later, they were still caught up in the trauma still. it was like it had all happened last week. their ENTIRE identity revolved around being victimized and every experience and situation was viewed through that warped lens.
i saw that over and over, and have seen that kind of behavior in others, not just sex assault. it's really a heartbreaking thing before the issue of "whether abortion is wrong" even comes up.
