When Did Your Cravings Start?

I'm possibly 9 weeks (haven't been to doctor yet) and I am having cravings. I don't find it that odd because even around my period times I would get cravings, but I've heard some people say "you don't get cravings that early". I don't give two craps what they say, but I am now interested to know when other women got cravings. (Plus I've known some women to say they never got cravings.) So, when did it start for you...if it ever did?
