Heightened sense of smell

I know it's common during pregnancy to be able to sniff out anything, but I didn't have that ability with my previous pregnancy. This time around I have that super human power. I've been struggling with a stuffy nose for over a week now. I think part of it is allergies and part of it is pregnancy related. Even though I really can't breathe, I've been able to smell items no one else can. I discovered this weekend that Goldfish crackers have cinnamon in them. There's no confirmation since all they list in their ingredients is "spices", but I am so positive there is that I would be willing to call the company that makes them and ask. This is just one example, there are others, but I won't bore you with them all.
