Seeking advise: chesty cough

Hi Mommies, I'm 22wks pregnant and suffering from chesty cough. It's painful and difficult to sleep at night. I have to take cough syrup to help me through the night and get enough rest. Is this cough syrup ok to take for pregnant women? Otherwise, what cough syrup is ok? What home remedies for chesty cough do you have? #pleasehelp #pregnancy #advicepls #1stimemom
