Sick in my 3rd trimester !

Im almost 33 weeks and im sick. My ears hurt, ive got clear mucus (most the time so far), my throat is always bothering me cause post nasal drip. My body hurts. No fever that i know of but we dont use medicine in my house unless you have a real deal fever. Im already worried that the baby will come sooner. What happens if im sick when the baby is born? What homeopathic things can i try that are safe? Is tylenol pm safe when in 3rd trimester incase necessary?
