I'm sorry if I came across implying this is the case for you. It was more of an observation that the reverse may happen. If you're rather reserved it might be that people are trying to fill in the pause, because it makes them uncomfortable, but actually interrupting you. I'm not sure what to do about that. Maybe some non-verbal cues that you're not done might help, like using your hands to illustrate your point, and not lowering them during the pause.
