I have been a waitress for over two years. Now That I am 7 weeks pregnant it's a whole new ball game. After long shifts I head to bed only to wake a few hours later to painful cramping, I know I should be fine to work this early in my pregnancy, And I know I should expect cramping while I'm growing, But I can't help worrying I am hurting my pregnancy. Does anyone else have cramping issues do to work?
