What if my aunt delays every month?

If from the beginning of menstruation, menstrual cycle is relatively long, more than 1 month, as long as it is regular, menstrual volume, menstrual color has not changed, you can not intervene, because everyone has their own menstrual cycle, as long as it is regular, in the clinical absence of any symptoms do not need to give treatment. However, if menstruation is delayed, such as once every 35 days this month and once every 40 days next month, this situation belongs to menstrual disorders and needs to be treated clinically. It is recommended that on the second or third day of menstruation, blood be taken to check the six items of sex hormones to understand whether it is due to menstrual delay caused by polycystic ovary syndrome, and then treatment be given.
