No cravings that I can remember.
But definite heartburn, swollen legs, back ache, ciattica for number 3 which probably helped me decide that number 4 wasn't an option,, overactive libido (probably because I couldn't get pregnant), numerous trips to the toilet,

and to add a new one to the list: sore breasts (that was an indication that I was pregnant).

Oh the good old days....
