how long to develop regular menses after menarche
Menarche(say âMEN-ar-keeâ) is the first menstrual flow or menses of a woman. It marks the beginning of fertility, that is, your ability to become pregnant. Menopause marks the end of menstrual flow, usually after about 30to 40 years of monthly menses.
A menstrual cycle is counted from the first day of bleeding in one month to the first day of bleeding in the next month. The average menstrual cycle is about 28 days, but cycles that are 21â45 days also are normal. It may take 6 years or more after your period starts for your cycle to get regular.
