For anyone curious- this can happen due to periods, the iron in the blood sets off the system. Also if you have a different package down there than one would assume you’d have, then that would also set off the system. Just anything out of the norm would set it off.
To my understanding at least.
If it's the kind of scanner I think it is, it just uses microwaves to detect any surface-level abnormalities under your clothes. It doesn't scan through your body like an x-ray, and it most certainly does not react to iron levels.
But maybe American airports use super fancy machines that do? I don't know, I haven't gone through an American airport in over a decade.
