Usage

Ought1 forms its negative in a number of ways. Ought not occurs in all types of speech and writing and is fully standard: The conferees ought not to waste time on protocol. Oughtn't, largely a spoken form, is found mainly in the Midland and Southern dialects of the United States, where it is almost the universal form. Hadn't ought is a common spoken form in the Northern dialect area. It is sometimes condemned in usage guides and is uncommon in educated speech except of the most informal variety. Didn't ought and shouldn't ought are considered nonstandard. Both positive and negative forms of ought are almost always followed by the infinitive form: We ought to go now. You ought not to worry about it. Occasionally, to is omitted after the negative construction: Congress ought not adjourn without considering this bill.

In correct English, ought is not used with did or had. I ought not to do it, not I didn't ought to do it ; I ought not to have done it, not I hadn't ought to have done it
