Sick and 25 weeks

Jessica • I am 28, married, we have a 6 yr old boy and currently pregnant with our daughter :)
So I am 25 weeks today! But have been sick with a chest and head cold for a week now. My ears are plugged and I have sinus pressure and my nose is plugged and my throat hurts so bad!! My doctor told me I can take nasal decongestant which I have been but it doesn't seem to be getting better. Is there anything I can take to help me feel better?
