I understand the pregnancy rule. It was brought home to me when I had a doctor friend come over and check me out for a sinus infection when I was about 35. Usually, his wife, a nurse practitioner and a close friend, did this for me, but she was unavailable. He asked me the p question, even though he was the one that referred my DH to the doc who did his vasectomy! I burst out laughing, but I *could* have been fooling around...
