Can the weather be too cold to postpone menstruation?
Delayed menstruation, also known as "rare menstruation", "after menstruation" and "overdue menstruation", is a common type of menstrual disorder. Female menstrual cycle is generally 2 1 ~ 35 days, with an average of 28 days. It is within the normal range to advance or postpone for about 7 days, and the cycle length varies from person to person. But if you haven't menstruated for more than 7 days, it is delayed menstruation. Various factors affecting female central nervous system-hypothalamus-pituitary-ovary axis and uterus may lead to delayed menstruation. It can occur in menstrual cycles with or without ovulation. Women of childbearing age should first rule out pregnancy when they find that their menstruation is delayed by more than 10 days.
