Am 36 weeks pregnant and last night when I was running a bath I got an overwhelming urge to taste the bubble bath! 
I didn't but something in the smell made my mouth water. Proceeded to spend the next twenty minutes smelling the other soaps, shampoos and bubbles in the bathroom. Anyone else had this?
With my first pregnancy I craved ice and would sit and crunch ice cubes all day to the great annoyance of my husband. That turned out to be a common craving if you are anaemic though.
