Sick 😔and 22 weeks

I was working at camp when we got a pile of really smoke from forest fires roll in. I couldnt leave because I was working but I got sick on day 2 of the smoke being there I was in it for a week. I went to the hospital and the doctor said that I deffently have a respiratory infection but thinks its strep. I have a really bad caugh and can't seem to be able to take anything for it. Right now I'm gurgaling salt and drinking lemon and honey mixes. Is there anything else I can do to get better quicker for my baby?
