I'm not sure if I'm 'different' but I don't really think about the EDD, more the date of the m/c. Though every now & again the thought comes up that I would have a ? year old now.

At the end of next month/beginning of Feb is anniversaries of 2 of my m/c. Not much is generally said in my house, it is just 'known'.
But I always feel lucky that my DD is with me & she gets the extra cuddles on those days.
