Or halfway-developed embryos, as the case may be.
I haven't been having any morning sickness, but I've been having food cravings and aversions like mad. Yesterday they got combined into one. I got home from school and could not think about anything except eating a delicious crunchy sweet wonderful apple. So I found myself an apple, and bit into it, and it was amazing. And then two bites later the aversion kicked in and suddenly there was nothing on earth that sounded more revolting and horrifying than a horrible disgusting apple, and I just about threw up all over myself, since I was in the midst of eating it.
Not cool, Buckethead.
