I'm Co-Founder of http://vantage.sh/ http://vantage.sh/ and we allow you to connect your AWS account(s) and we'll monitor cloud spend on your behalf. We send out regular cost report emails to try and help folks avoid situations like this and have some future plans around anomaly detection to try and help out in advance of things like this happening. I strongly encourage folks to sign up and let us monitor things on your behalf. We have a free tier that likely covers a lot of personal users here.
