period cramps in cis women are due to prostaglandins causing uterine tissue to contract, which obviously isn’t possible in trans women.

However, trans women on estrogen can experience cyclical PMS symptoms, so it’s not totally unfair to say there is some overlap with periods that way.

I also suspect there can be bowel discomforts during the PMS that get conflated with period cramps, so that makes sense too.

Obviously trans women don’t experience period cramps in the way cis women do, and don’t have menstruation.
