5 weeks with a cold

Mom • My name is Raschel. I`m married and have a wonderful 4 year old son and a beautiful rainbow baby girl born nov 2016.
I'm 5 weeks pregnant with a bad cold.  It started out as aches and pains and I was up all night with a mucusy cough and a severe sore throat. I called my dr and asked if there was anything I could take. She said sudafed or robitisson. Has anyone else been given the go ahead? I'm nervous to take anything...
