Dry cough 2 week old?

S

My daughter has coughed a few times since 3/4, it sounds dumb but it's a dry cough(not more than once or twice at a time) and I havent noticed any other symptoms besides that she has a doctors appointment on the 23rd for her two weeks but if she doesnt have any other symptoms would it be ok to hold off on the doctors until tuesday? Or should I call tomorrow morning? Is it normal for them to occasionally cough?
