I'll give you some time to read up on some actual science...not that I expect any reply back.

if you think a google search for stress miscarriage cortisol constitutes actual science , there is even less hope for you.
I want to start by stating I read every link on the first page of the search you provided. However, if you would indulge me, I have a couple of comments before I address my findings.
First, I cannot help but remark that you are significantly moving the goalposts by abandoning rarity of conception in favor of miscarrying.
Second, I noticed a profound absence of any attempt on your part to link elevated cortisol with rape victims. This may just be an oversight on your part, but without it your position is a non-starter. If you would be so kind as to provide links to support this premise it would be much appreciated.
That said, on to the Google-provided information....
Most of the linked articles cited one or more of three studies - one of 61 married women in Guatemala, one by the University of Berlin, and a 1997 study of pregnant workaholic female attorneys. Additionally, one linked article on about.com cited other studies and questionnaires, some of which found links between elevated cortisol and miscarriages and some that didn't. What stood out the most was that elevated cortisol levels attributed to stress is very likely linked to a higher risk of miscarriage, but could not be conclusively identified as the primary (or even a significant) cause of miscarriages.
In other words, no study was able to conclude if elevated cortisol caused miscarriages, impending miscarriages caused elevated cortisol, or other factors caused both the miscarriages and the raised cortisol levels. The researchers of all the studies made sure they were clear on this point.
One final note: none of these articles have anything whatsoever to do with the acute trauma associated with rape somehow reducing the possibility of conception. You are mistakenly presenting studies on the effects of prolonged elevated stress on existing pregnancies as a very clumsy attempt to support your desire to prove an absurd claim.
Have a good night.
