Thanks for sharing LimeSlice. It really aggravated me when I went to my first doc appt and scan knowing that I have a longer cycle and ovulate later, therefore knew when my EDD was likely to be, only to be told by the so called experts that my calculations were wrong and they moved my dates a week forward based on my LMP even though the scan proved otherwise. Thankfully, my OB actually agreed with my dates

When people ask me when am I due I simply say January and they get all funny when I don't give them an exact date, they can't process the idea or something.
