I am pregnant with my 3rd child and wondering if Advair will keep me from going into labor. When I was pregnant with my first child I was taking Theodur and Proventil, which did keep me from going into labor (induced at 42 weeks). This time I am only taking Advair (lets hear it for new meds!) but wondering if the same thing about labor applies. I was on Serevent and Asmacort with my second but didn't have the same problem as I did with the first. I am 39 weeks with number 3.
