It's an easy parallel to draw especially since many times the two situations intertwine: trying-to-conceive bears many similarities to trying-to-partner. In both cases, we believe the timing is within our control until we discover that life has its own timetable. We can put in hours and hours of hope and hard work and have nothing to show for it on the other end. It may be the thing we want most, but the only aspect of our life that is completely out of reach. Both situations can move like a roller coaster once the tame ride picks up steam after the first twist or drop.
