So Annie and I keep arguing over whether we are in the final trimester of our pregnancy or not. I say that simple math prevails, counting boldly on thumb and two fingers,
"June 20th to July 20th. July 20th to August 20th. August 20th to September 20th. That is three months. TRImester!" Annie rebuts with some technical explanation of weeks to term and an algorithm that calculates from last menstruation to due date. I sigh and concede that the professionals who devised these calculations are much more experienced at this than I.
