depends... Did you use energizer, or nutrient in the fermenter? Did you make a starter? What kind of yeast did you use? What kind of ingredients did you use?
All these factore have a role in how fast the fermentation starts.
however, I am sure that the fermentation will be fine. Sometimes it just takes longer than others.
Yeast needs to acclimate to thier enviroment and there is always a lag time before they start to aggressivly eat the sugars.
If after 4 or 5 days nothing happens, then I would be concerned.
