a) I find this really, really interesting as a mom of three girls and one lost boy. When we conceived our son, it took seven months of trying, which was really surprising to us after the first two girls were conceived within three months each. This third one (where I was trying to sway blue less than six months after the birth and loss of my son) worked on the first try. I had just assumed that the changes I had made to attempt to be blue had improved my fertility and made it possible to conceive so quickly, but maybe there is more to it, as you say. I know that we have a number of strong pink factors working against us (especially from my husband), but perhaps reduced fertility is part of it as well.
