Have you checked with your OB? Some providers even have sites with medicines listed out. My RE (still transferring to an OB) allows me to take Guaifenesin (active ingredient in children's Robitussin) which thins mucous (which may be causing your soar throat and coughing). For body aches you could take good old Acetaminophen (Tylenol).
See if you can search this? A few days ago someone else asked. I was sick and my RE told me what we could take but unfortunately I don't remember! Many Meds are prohibited!
