Sick and need help

I am 29wks and 4 days as of today and woke up with either a sinus infection or allergies Monday morning. Monday it was a sore throat, Tuesday it was a stuffy nose and headache, today I feel like I have a fever and am completely stuffed up. I have been drinking water, ACV, honey and have rinsed out my sinuses with salt water. Does anyone have any other suggestions ? I prefer to try to heal without medication. I’ve been resting as much as possible but can’t as much as I want to due to my job. Open to any natural remedies I missed!
