It's funny how reading from what to expect can make you paranoid. My intuition tells me I am not prego, but when you read about your sense of smell and think of at least 4 scent related items that are prominent in your mind immediately there after, it does give you pause.
I admit, the smell of my tenant's food has crunched my nose and nearly turned my stomach a couple times this week, but I think it's because I've already been nauseous in the evenings - attributed to med withdrawal. Fun times.
