Is my nose sensitive or what!

This pregnancy has been about different sorts of experiences. From crazy nausea to hyper tiredness, from feeling sick most of the time to feeling good about feeling good, it's been an interesting ride. However, another big change I've seen is the hyper-sensitivity of my nose to not so nice smells. BO, the smell that emanates from someone back from a smoke break ... anything triggers nausea and I really need to rush away from the source of the smell. No more on this, even thinking about it as I write makes me feel ugh!
