My nose has been driving me crazy. There are some scents that trigger m/s and others that I can't get enough of.
Right now, it's the smell of our new appliances when they heat up (especially the oven) that make me so sick. The dishwasher, stove and toaster bother me too (they're all brand new so it's that burning plastic smell, bleh!)
I'm loving the smell of clean laundry and powdery perfume...so unlike me.
Last pregnancy, it was coffee.

So what makes your stomach turn? What scents do you love right now?
