AWS has tools to set spending thresholds and to alert when you go over. Set those up first thing. Regularly (daily) check your usage in the dashboard and stop things before they get out of hand. You will eventually accidentally spend more than you want to. This is a feature. Just try to catch it early and course correct before annoying becomes disaster.
