My crewmate and me recently delivered twins, to a couple who rang NHS direct asking for advise for abdo pain, twenty mins later the nurse at NHSD rang back, and asked the standard questions, and the answers didn't relate to any of the usual ailments i.e food poisoning, appendicittis etc., after several more minutes, the nurse was becoming baffled at this ladies predicament, so as a last ditched effort asked if she was pregnant, "oh yes, i'm due to induced next Tuesday", best call an Ambulance then was the nurses reply. So even if they do know they're pregnant, they are still thick as shit!! the twins were fine, spent a few days on SCBU, then the parents forgot to go and pick them up!!!
