I printed out a nine month calendar from the internet that had a day by day explanation of what was happening to the embryo, then fetus, etc., etc. I hung it on my wall, it was huge! Everyday I could look at it and see exactly what day I was and what was going on.
It was personalized with my due date, also, and it was right!
P.S. Maybe that was a little like watching water boil, though, and maybe it would make it longer, I don't know.
