So sick and MISERABLE:(

I have a super bad cold, my asthma is even coming back with it and the doc gave me 2 inhalers. I've read risks about the inhalers and just don't feel like the benefits outweigh the risks. (I haven't even taken one Tylenol since getting pregnant.) I am now 24 weeks... Is it safe for me to take mucinex? Please let me know, I'm totally miserable. Thanks!
