A member asked:

If my lmp was 05/27/13 and my ob told me i am 13 6/7 today 09/10/13.do i count back to see when i conceived? i have irregular periods if that matters

Base on size: Your conception date and your baby's gestational age are more closely associated than your LMP is with gestational age. Baby's size is going to be determined by average growth of embryo based on # of day alive. Thus your likely cd was, and still is, 6/19.
