Not all age-related changes to your period will occur in older people.
It may take a little while for your period to happen every month.
Perimenopause
Perimenopauseis the period of transition between reproductive age and a non-reproductive age.
Menopause
Menopauseoccurs as you reach an age when you will no longer ovulate or menstruate.
The average age of menopause is 51 years old.
It is sometimes called premature ovarian failure.
This can cause irregular periods and fertility problems to begin before the typical age of perimenopause.
