Thanks Alexis - that was great reading. I was talking to a lady the other week - think she was a midwife or doula and she was say that your due date can also be effected by your ethnicity. Most caucasion pregnancies are 41 weeks while African pregnancies tend to be 38 weeks. Apparently there is also a family somewhere and all the woman in that family have some abnormally short gestation but there babies are born "full term" so for them they have a marked shorter gestation then most people - very interesting!
