Something I never knew about pregnancy is that it can really increase your sensitivity to smell.  And not just to odors that would normally make your nose wrinkle, but everyday smells that you might ordinarily notice but dismiss suddenly become beyond offensive.   Roasting Fish.  Perfume Counter in Macy’s.  BBQ Sauce.

Of course ordinarily foul odors become even more so.  Doggy Poo.  Garbage Cans.  Shudder.
