Girls, hello! Can you tell me about week 40.1? We're expecting a baby girl. We're sitting quietly for now, no signs yet. We had an appointment with the midwife today, examination on the chair, someone has been there before, can the doctor pierce the mucus plug during the examination? Or does it just have to go away by itself?
