Mending heart

Over the last week or so I've notice something strange. When I see pregnant people, babies or young children I'm not struck in the heart with painful longing. Sometimes a little twinge of sadness but only for a moment. How did this come about? Is my heart mending from the last 5 years of infertility? That seems too simple to be true. I'm expecting the pain to return. I'm sure I will have bad days again. Days when the loss of my chance to parent will strike me so hard I can't breathe. But this last week has shown me I can have good days too. Someday, the good days will outnumber the bad. It is like my heart is giving me a little taste of healing to tell me I can return from the "land of IF" whole even without a child.
