All of you ladies may want to sit down for this. I was thinking today "oh cool, I am almost twenty weeks along, that's five months, sweet!" so then I continued to ponder, "hmm, so that means I have four months left...how many weeks is that? four times four is sixteen. Cool sixteen weeks left." Wait a second! I don't have sixteen weeks left, I have twenty weeks left. Pregnancy is TEN months. Is it just me because I thought it was supposed to only be nine. I feel a little cheated.
