Getting sick :(

This is the second time I have been sick since I have been pregnant...my sinuses are so swollen causing ear aches, head aches, coughing and even hurting my eyes. My doctor said I could take Chloe-trimeton, but it doesn't help too much and I would rather not  take anything at all. On top of that, I'm scared that being so miserable and sick is bad for my baby. I'm 27 weeks and it's getting harder to move normally, let alone being sick too. I'm also a full time server and the exhaustion is making everything worse. Does anyone else have this problem or any idea how to make it better?
