It's such a weird part of pregnancy isn't it? The horribly heightened sense of smell that can send you gagging. My worst is fridges, including the smell of refrigerated foods in the supermarket - ugh! Also the smell of baked goods in cafes, which is weird as I still like eating cake & bread. Sometimes I think I can smell something rank rotting in our cellar, but DH assures me there is no real smell... I'm 14 weeks, hope it (and the nausea) goes soon.
