Hi Megg. I was on the due in NOv thread too and I also miscarried in April. I thought I had moved on but a few weeks ago I went through what you are describing now. It's like it creeps up on you and we feel that we shouldn't be upset anymore. But why shouldn't we.
I still often think I would be x months pregnant now, and I don't know how I'll be on 24 Nov (my due date) but like tamba says, I try to focus on what I have and how lucky I am.
I am also focusing on not having another baby just yet (defense mechanisim maybe?)and don't know what the future has in store for me.
Sorry for rambling, just wanted to say its OK to still be sad. I felt taht I hadn't doe anything to signify/remember what might have been, and a very good friend of mine bought me a beautiful samsoite jasper stone in the shape of a heart, which I keep in a special place and take it out when I feel like a good cry and put it away when I'm done. It truly was the most helpful thing anyone did and I will treasure it always.
Take care, hope you feel better soon.
Bet your ds keeps you busy! How old is he? (mine is 4)
