Since this is my third, I am now quite sure I can attribute these to pregnancy as they have happened repeatedly. Some strange things that happen to me when pregnant:
1. I lose my vocabulary. I speak. There is a word for what I'm trying to say. I used to know it. Can't remember it. (Luckily, this goes away, but SO annoying while pregnant).
2. My FINGERS get skinner. Nothing else. I am average height/weight. I've gained on the higher side of average for all my pregnancies. My wedding ring starts falling off when I'm pregnant and ONLY when I'm pregnant.
3. I drop things like crazy. I used to think it was a cruel thing to have to bend over and pick things up all the time while pregnant, but I later learned it was just practice for doing the same while holding a baby, because if I'm not dropping something, they are, or throwing it...
4. I'm OBSESSED with chewing ice. I happen to know this is iron-deficiency related, but it's beyond a simple craving. Drives my husband nuts. Even driving my 5 year old nuts, apparently, but I CAN.NOT.STOP.
Spill it gals, what weird pregnancy things do you have going on...

My hunger goes from 0 to 60. I'll be fine one minute and the next I feel like I'm going to kill everyone around me if they don't get me food immediately. Needless to say I try to keep snacks around!!
I have a friend from Eastern Europe who calls dishwashers "dishers" and washing machines "clothes dishers."
