HELP ME!!! MY FACE BURNS

Mary
The very first symptom of pregnancy I've had is sensitivity to odors, and it keeps getting worse. Certain scents such as perfumes, regular body soaps, and lotions really irritate my nose. Whenever I breathe in a certain scent that irritates me, a burning sensation spreads from my nose throughout my whole face. Before I found out I was pregnant, I took sinus medication for that sensation because I just assumed it was sinuses. Of course that just made me drowsy. I tried breathing through tissues as a way to 'filter' the scents, but it just doesn't help at all. And it is very inconvenient while I'm out in public. I work at a mall, so perfume and soaps are everywhere. It's so hard to work while my face feels like it's on fire!!! Can someone help me :(
