Doctor's answer:
It's not easy to determine. The menstrual cycle of women is generally 28 to 30 days. It's still within the normal range if it's advanced or delayed by about 7 days. The length of the cycle varies from person to person. However, if menstruation has not arrived after more than 7 days, it is considered delayed.
