Spidey Senses Gone Wrong

I've had the most incredible sense of smell since becoming pregnant. I can identify whether the Cheerios the person 3 cubicles over is eating are plain or honey nut. I can tell if the person that just entered the building 50 yards away is a smoker or not. For some reason the candle that the lady across the hall has always smells like cat pee to my new nose, and the new fragrance that comes out of the bathroom odor eliminator smells like flowery poo to me, even when I know no poo has been there. Bleh. I do not work in the best environment to be super sensitive to smell. Today was no exception to that rule. I saw a woman today who smelled so strongly like a dog kennel to me that it was completly overwhelming. I tried the ol' fragrant-lotion-on-the-hand trick to try and drown it out to no avail. I ended up dry heaving in front of the poor, smelly lady 3 or 4 times before I had to leave the room. I tried to explain to her that I was pregnant and I don't think she caught on to how offended I was by her odor, but I couldn't finish helping her. I had to have someone else take over. I feel so bad/rude that I almost lost it in front of her and I'm still super embarrassed that I couldn't control my vom-reflex this far into the game. Does this last until birth, or can I look forward to normal senses sometime soon? I see way too many less-than-clean parents and children in my line of work to spend another 20 weeks heaving at the first sign of poor hygeine.
