Does God really instruct us to "rip up" pregnant women?

No, and remember not to read Scriptures out of context. You can't understand the reasons God has for anything unless you are one of his children. I know how frustrating it is to read stuff and try to understand, but what is the purpose of reading the Bible if not to get closer to God and understand what he is saying? If you read the Bible for the wrong reasons, like looking for bloodshed and things that don't make sense in our world today, and contradictions, then you will never see the truth.
