Asthma/inhaler/pregnant

Hi all, 
I'm 27 and been a severe asthmatic since I was 18months I've used an albuterol inhaler my whole life, a nebulizer, and have even been on oxygen 24/7 for a period of time. My asthma has improved greatly over the last few years which I'm truly grateful for and only take my inhaler when sick, weather change, or before working out but not usually on a daily basis. I am now 13w pregnant and have been having to take my inhaler almost every day for the last week  which I am truly terrified about doing, I know it's better to take it and breathe than not. I don't meet with my doctor till the 14th and wondering if anyone has had to take an inhaler as well during pregnancy ?
