Pregnancy in rape will be only a small percentage of pregnancies only because rape isn't THAT common and the odds of getting pregnant is about 3-5% from NORMAL one time sex. To be clear if you have sex with a random woman of child bearing age without protection the odds of getting pregnant are 3-5% as she may not be ovulating, and even if she is it may not take.
