I know this is an old thread. This post is for people, like me who may be currently researching this topic. The only time I crave sweets and chocolate is right before, and the first one and maybe second day of my moon. I'm on Day 7 of my fast. My BBT just dropped, so I'm expecting my moon in the next one to two days. I don't feel any cravings for sweets. I do feel the slight cramping that lets me know that my uterus is preparing.
