Some bronchodilating medications (most notably terbutaline or bricanyl) are actually given to slow labor. Other bronchodilating drugs have the same effect but to dose high enough to get an actual effect on your pregnancy would cause some serious cardiac side-effects, unless you're predisposed to be the type who doesn't go into labor quickly and easily.
Truth be told, just because you were induced doesn't mean it was your asthma meds that kept you from going into labor -- but it can't be proven that it wasn't, either.
Go look up infofrmation on Serevent, as that'll be the drug you're worried about. Flovent (the other component of Advair) won't keep you from going into labor, but I highly recommend you do the drug research yourself.
