Do I need to redo it, is it ok?
To answer your question, you don't have to redo it, as long as you didn't put TOO MUCH paste on it, and as long as the heatsink is installed properly, sitting right on top of the cpu. A little bleeding out is okay, and many people do it by mistake. From my experience, I would rather have a little extra than little less paste.
