Welcome to the Forum Maria. When you post it is good to give some context - often there are many ways to say something and it depends on your original sentence. Without having context you could also say: No era mi intención. If you did something, for example break something: No lo hice adrede. Another translation: ¡Fue sin querer!
Yo no quise..... Yo no quería.... (e.g. lastimarte)
