dp worse during/before menstruation

hi everyone im a female and am currently on my period. i had a bad episode of dp today during a test (im in highschool) and I've noticed that before/during that time of the month my symptoms are particularly worse. why does this happen?? is it because of the change in hormones?

i had a standardized test today in school and I think it triggered my dp, especially the math portion because that always seems to be anxiety-inducing for me. it is also noteworthy to mention that my dp is completely anxiety-induced (to my knowledge i do not have the disorder). the fluorescent lights in the room definitely didn't help either.. I've noticed that they exacerbate my symptoms.

an explanation to all this would be helpful
thanks
