Of course there are many women who long for a child that never comes, and I feel fortunate that I have never been at that point in life. I think my doubts about having children started relatively early, when I found out how they came out. I still have doubts about that!
When I found out there is a massive online community called Gateway Women for childless women, I should have been less surprised. I have come to the realisation that life without children is pretty awesome, and a lot better for my health. Except maybe for all of the candycanes I don't have to share.
