Wanting some support

Katie
Hi All- 
I'm 8w1d and I have viral bronchitis and feel so terrible. I'm afraid to take any of the medications but they're telling me to take Tylenol and Zyrtec to try and dry some of the mucous in my lungs. I've been sick for over a week and just feel exhausted. I'm also terrified I'm hurting my baby with these medicines and by being sick. Anyone been through this and had a healthy baby? Thanks!
