I took tylenol severe cold warming liquid.. It helped me :) they have a few different types for different symptoms as well.
Mine told me to take claritin and then after that didnt work he prescribed me something else.
There ate antibiotics that ate safe to take during pregnancy! However if you don't have an infection you may be limited to cough drops and saline nasal spray since most sinus/cough meds contain pseudoephedrine and/or phenylephrine
