Mary is at least three months along in her pregnancy when Doc Baker confirms it to her, and yet she never even has the slightest bump. You'd think she'd at least have her blouse untucked to show that she is expecting, but she never does. Even though it's implied that she miscarries early, she never looked pregnant at all.
Reply: It depends on a person's body type. Many woman do not start showing till they are four or four and a half months along. Also, she might have been showing a little bit, but her clothes hid her bump.
