I have a young friend who recently gave birth. What tipped me off that she was pregnant was that smells made her sick...even her husband who never bothered her before. (Thank goodness for both of them, it didn't last long) It wasn't just food.
Personally, I walked around surreptitiously massaging the sides of my breasts when I became pregnant. I didn't know what it meant for child #1, but in my other pregnancies, I knew within days of conception I was pregnant. And a colleague of mine (female with children of her own told me when she saw what I thought was the surrpetitious massaging that I might be pregnant.)
Otherwise, I think I walked around with a dumb smile on my face for nine months!
gerry
