Pregnancy Question

A woman pregnant with her first child paid a visit to her obstetrician's office. After the exam, she shyly said, "My husband wants me to ask you...," to which the doctor replies, "I know, I know," placing a reassuring hand on her shoulder. "I get asked that all the time. Sex is fine until late in the pregnancy." "No, that's not it," the woman confessed. "He wants to know if I can still mow the lawn."
