Hi sarah, I have presented preliminary findings at a conference although they were quantitative, but I did have to write an abstract to present a qualitative study once before I had done the analysis! I think it's absolutely fine to say that it's a work in progress and to just present any emerging themes and give an idea of how common the themes are if possible at this stage. I would definitely include quotes- I think doing that helps to keep the audience awake! You can also go on to say what you will do next and how you expect things to turn out. I wouldn't worry too much- plenty of people present work in progress and that won't make it any less interesting or valuable for the audience. Good luck with it, KB
