If you are concerned then you should but that is enough words at 15 months.
Is she babbling as well?
My daughter had no words at 21 months and no babbling at all. In our state they need a 50 percent age delay to qualify or 2 areas of delay at 25 percent each (of their age).
Cant hurt to call, but it sounds like she is doing pretty good in the speech area!
