I have an undergraduate degree in Education (international) with a 4.0GPA, a Masters in Communication from the U.S. with a 4.0 as well, good recommendations, three years of teaching and work experience, three languages BUT a 159v/144q GRE, and no publications or conferences at all. I'm afraid PhD programs are very likely to reject someone with no publications or conferences at all. We will see!! I think you have a good chance as long as your research intent is a good match for them.
