Am I the only one?

I have terrible sinus issues and headaches before pregnancy, but now being pregnant it seems 10 times worse and nothing relieves it! My head throbs all day and my sinuses burn. I take zyrtec, nasal spray and musinex for the past week in a half and it helped for a day or so and then came back ten times worse. Please tell me I'm not the only one with these issues?!
