Asthma and cold while pregnant

Jamie • Family is the most important thing in the world.
I am just looking for some kind of relief. I see my doctor this week but something in the meantime would really help. I am very wheezy and am having to use my rescue inhaler way more than I usually do. I know it's better to use the inhaler than to take the chance of the baby not getting enough oxygen, but I'm also worried I'm using it too much. 
Anyone have anything they have found to help in this kind of situation?
