Did anyone's asthma get worse in pregnancy? If so, how did you keep it under control?

I have very mild asthma (exercise and allergy induced)
I've probably used my inhaer a total of 2-3 times in the past 18 months and even so, it's because f coughing/wheezing not because of a major attack.

The past two days I've been coughing and wheezing a lot. It feels Asthma related vs illness related. If it doesn't go away tomorrow I'm going to call my doc...but wondered if anyone ad any stories or advice to share.
