With my DS, we went to 43w2d and now I am expecting number two, I am not worried. Going by LMP, I am due 16th August 2011. All three of the pregnancies that I have had ultrasounds with, have shown my babies measuring two weeks behind. My dating scan has me at the 31st August 2011. I believe that my LMP is the most accurate in determining the age of my baby but only my body will be accurate in predicting my actual due date. Belief is that you are not allowed to go beyond 14days "overdue" so I am lucky that I measure behind otherwise I would not have been able to go into labour naturally with DS. This time, I have had the 13th of September come to me and so I was chatting to my midwife about what will happen if I have not given birth by the 14th. She informed me that I do not have to be induced but I will have very regular checkups to make sure that both bub and the placenta are doing fine. With this monitoring, assuming that everything stays fine, I will be able to birth whenever my body sees fit. This has greatly assured me. I do not know why I am so at peace with letting things run their course this time as I was so angry with how far I was let to go over last time but I am glad that it happened and I cannot wait for this new and exciting experience of a flowing birth
