Have you had any non-food craving during your pregnancy? Is it normal to want to eat chalk or coal?

Ooooh! Interesting! This one's new to me and I just learned they have a term for it. Thanks for asking and for Idza answering. :) But if I am to share my non-food craving during my pregnancy, I guess it's craving for my partner's presence all the time! Haha! Not only because I adored his face very much that time (ya, cheesy I know^^) but also to squeeze his hand, bite his arms everytime I can feel something painful most especially in my throat after I threw up due to morning sickness (that goes morning til end of work shift).
