Things to Know About Menstrual Delay

Menstruation usually runs on a monthly cycle. This is the process a woman’s body goes through as it prepares for possible pregnancy. During this process, an egg will be released from the ovaries. If this egg is not fertilized, the lining of the uterus is shed from the vagina during a woman’s menstrual period.

Your menstrual period, also known as a period, usually lasts two to eight days.

Many women experience symptoms during their periods. Some symptoms, such as cramping or mood changes, may begin before the menstrual period. This is often called premenstrual syndrome or PMS. Most women’s menstrual symptoms go away after their period ends.

How Long Does a Full Menstrual Cycle Take?

The full menstrual cycle is counted from the first day of one period to the first day of another. It usually takes 21 to 35 days. There are different stages in the menstrual cycle. These:

follicular phase

The follicular phase begins on the first day of menstruation and ends when ovulation begins. At this stage, the ovaries produce follicles that then house eggs. This stimulates the thickening of the lining of the uterus. During this time, there is an increase in estrogen.


The mature egg is released into the fallopian tube and then into the uterus. This typically occurs in about two weeks or about halfway through a woman’s cycle (the day that is mid-cycle).

luteal phase

The body maintains its preparation for pregnancy. This includes an increase in progesterone and a small amount of estrogen. If a fertilized egg is not implanted in the uterus, this stage will end and menstruation will begin. In a 28-day cycle, this phase ends around day 22.

Menstrual Period

At this stage, the thickened lining of the uterus is shed.

How is the menstrual period regulated?

Many women like to regulate their menstrual cycle. Regulating the menstrual cycle focuses on strategies and treatments to ensure that a woman’s period is within a specific time frame and lasts between “normal” for a period of two to eight days.

The most common way to regulate the menstrual cycle is with birth control pills or other similar hormonal contraceptives such as the patch or NuvaRing. Some of these contraceptive methods will trigger a woman’s period once a month, while others may give her a period every three or six months.

Other methods of regulating the menstrual cycle may include treating eating disorders that cause severe weight loss or changing diet and lifestyle. If you can reduce stress, that can also reduce the irregularity of your period.
