Anything that interferes with normal ovulation can cause your period to be late or to become irregular. Premature Menopause Every woman is born with around 1 to 3 million eggs. Every time she ovulates she releases one of these eggs. She also loses some of her eggs as she ages.
It's normal to have an irregular cycle or two now and then. But if you continue to have irregular periods, or if you don't have a period at all for three to six months, it's time to see your doctor. Most menstrual cycle intervals occur about every four weeks, with the normal range between 21 and 35 days. To calculate your menstrual cycle, start counting from the first day of your last period and stop counting on the first day of your next period.
