I have an upcoming presentation in an international conference in a bit more than a month. I wrote the abstract for my presentation in February, in which I said I would present early results. It is even in the title of my submission: "presentation of [project] and first results". However, I am progressing much slower than I expected and I will probably not have results by then.
What can I do? My coworker (project leader) and I have already paid for the participation and prepared the trip, which is a big expense for our project. Can I just send an email to the conference saying "actually, I will not include results in my presentation" and attach a new abstract? I feel amateur and lame. Or maybe, it is too late for me to change? This terrifies me and I feel miserable.
I read this question and I feel like my case is a bit different because I specifically wrote that I would present results.
