Odd Cravings (not pregnant)

IMYarnCraz33

Over the last year, I've been getting what I call an odd craving. It doesn't happen often
but it concerns me somewhat.
Sometimes I get the craving for meat.
I don't know if my body is trying to tell me something (need more protein?) or what.
I am not a vegetarian or vegan or anything like that.
I haven't had any cravings in about a month or so.
Anyone have any ideas why I'd have that sort of craving? Has anyone else had this?
