Due date

So I had my first miscarriage back on August 22 last year and i thought I was “over it.” I know that sounds harsh, but I don’t know how else to describe it. I basically felt as though i had made peace with what had happened and tried to put it in the past. Now that I’m approaching my would be due date (tomorrow April 24) I am feeling so so sad about it again. I feel like I want to do something in memory of the baby I lost. What have any of you done?
