KT, not silly at all. FWIW you probably are having them, but you just won't feel them.
People describe them mostly as being a tightness across the bottom of your bump, but other's get them in their backs or even at the top of the bump.
Personally, they tend to make my whole bump go rock hard for 30 seconds or so and then it slowly softens back up.
MW's will tell you BH's never hurt, but I think they can do, hurt is probably too strong a word, but deffo uncomfortable at times.
