Is she the reason we have cramps?

Ok religious people I have a question I just thought about. 
Is <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> the reason we have period cramps and it hurts?
Did Jesus have to be nailed to the cross because of <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>? 
Why did she listen to the Surpant?
Did God knew she was going to all along? If so why didn't he prevent it?
I'm not bashing anything I'm just really curious
