InDesign doesn't come with a History panel, it never did. There are some third party solutions - 65bit Software and DTP Tools are the ones I know of. DTP's plugins are still in beta for CC, (windows version not even in beta), but you can buy a History plugin from 65bit - that is if you're using CC and not CC 2014. EasyHistory
As for the normal Edit > Undos, there should definetely more than one - I don't know how many, but there should be plenty ...
