Pregnancy and asthma!? Help plz!!!

Ally
I'm 18 weeks pregnant. Dr told me it was fine to keep using my inhaler but I'm still a little hesitant. I completely stopped using it my first trimester and thankfully I didn't need it. But I noticed that one I hit 16 weeks I've been getting more asthma attacks 🙈 have any of you used an inhaler through pregnancy? Do you have any other suggestions? Did you have complications during birth?
