Food cravings food aversions

One of the funny things about being pregnant is the way food affects you. All of a sudden now there are things that I can't stand. Like cinnamon gum not cinnamon in general just gum. Coarse ground pepper. I still like regular pepper just not the coarse ground pepper. And Japanese food, mainly teriyaki chicken and fired rice. Two months ago I still loved all of these things now the mere thought of them makes me want to gag. On the other hand there are things I crave that I didn't eat at all before or didn't eat very often. Like strawberry milkshakes, I liked milkshakes before but not really strawberry. Soft pretzels, I just bought a mega box of 36 at BJ's. Ice water, normally I like to drink water room temperature. Now I love ice water which is so strange to me.
