Treating Illness while Pregnant

Daisy
I've had a horrible head cold these past few days. Headaches, congestion, runny nose, diarrhea, low grade fever, etc. I've been using nasal saline spray, menthol chest rub, and cough drops (after researching and verifying they were safe after 12 weeks). Is there anything else I can do to make this misery easier or shorter? Thanks!
