Awww Pink ~ our lives are so parallel you wouldn't believe...
The same thing happened to me (a long time ago) and it was as if I were walking around in a state of confusion. A lot of people thought that as I hadn't planned to be pregnant and didn't even know I was, the miscarriage wouldn't affect me. Of course it did! however, it doesn't affect everyone and whatever you are feeling is *normal*.
The main thing to do is to rest up ~ grieve, take stock etc. Your body has gone through the mill so rest is important. The emotional side of things may take a little longer. If it doesn't take long, don't feel guilty. As I said, whateve you feel and how you deal with it is normal.
Take care, hun..thinking of you xxx
