At this stage if it was fertile it would look like something is inside. it is most likely infertile. I have had this happen plenty of times before most infertile eggs will mold and collapse during incubation
Sometimes they will be half empty water balloons right from the start other times they look good and will go bad several days or weeks into incubation . but on occasion you get one that does not mold or collapse its just empty.
