I felt like a dinosaur during my third trimester (a dinosaur with a lot of gas...see more about how I felt like a dinosaur during pregnancy at My 3rd Trimester of Pregnancy - Thunk! Thunk! Here I Come!), and I just wanted someone who could empathize with me about how fat my feet were and how much they hurt. Two books that kept my sense of humor [somewhat] alive at the end of my pregnancy were written by two different woman, Jenny McCarthy and Vicki Iovine, who offer two refreshing perspectives on the realities of pregnancy, and they are not "too polite to complain or too embarrassed to talk about the discomforts and humiliations of pregnancy."
