There is nothing at all about a woman's mindset that affects this. Women can't wish pregnancy away. If they could, then many teen pregnancies wouldn't occur; few teens want to get pregnant. But think of the larger picture. Women in abusive relationships get pregnant. Women in horrible socioeconomic conditions get pregnant. And, yes, women who have been raped get pregnant.

The body doesn't differentiate between "legitimate" rape and "illegitimate" rape -- whatever that is. The body doesn't know whether the rapist is known to a victim. The body doesn't know if a knife or a gun, or alcohol or drugs (or any combination of them), were used.
Every sexual encounter does not lead to pregnancy, but every sexual encounter leads to the possibility of pregnancy. Period.
