medicine exams..?
well if u had the others.. u might have blindness too or massive weight problems (lik pathological.. not like "I cant say no to chocolate") or a mass in ure pelvis.... so lik its all lik a big picture thing... its not just wally.. its the wizard too!...
also
hormone levels would tell us
and blood counts..
lots of fail safe mechanisms..
Endometriosis- she would be in so much pain and have such a large period.. also she would kill her signifiicant other.. especially if they asks for sex....
so no.. prolly not the cause of irregular or stopping period..
stress... weight loss... excessive exercise are usualli the culprits..
