You can decide to apply your 5th amendment right at any time, you just have to be explicit that you’re doing so (Salinas v. Texas). And then you have to stand strong in the face of attempts to get you to continue talking.

Oh, yes, I just meant that as long as you're saying things, your speech is not protected by the 5th amendment. Not that if you've started speaking you can no longer stop and invoke the 5th later.
