CHANGES IN MENSTRUAL CYCLE LENGTH? | Why It Happens & What You Need To Know!

Most girls get their first period between the ages of 10 and 15, but some get it earlier and some later. The first period is known as menarche .

A girl’s monthly cycle is the number of days from the start of her period to the start of the next time she gets her period. You often hear this is a 28-day cycle. But 28 is just an average figure that doctors use. Cycle lengths vary some are 24 days, some are 34 days. And a girl may notice that her cycles are different lengths each month especially for the few years after she first starts getting her period.

Early in a girl’s cycle, her ovaries start preparing one egg. At the same time, the lining of the uterus becomes thick to prepare a nesting place for a fertilized egg in the event that the girl becomes pregnant.

About 2 weeks before a girl gets her period, the egg is released from the ovary . The egg travels through the fallopian tube into the uterus. If the egg isn’t fertilized by sperm, it starts to fall apart. Then the lining and egg leave a girl’s body as her period and the whole thing starts all over again that’s why we use the word “cycle.” The first day a girl’s period comes is Day 1 of her cycle.

It’s also normal for the number of days a girl has her period to vary. Sometimes a girl may bleed for 2 days, sometimes it may last a week. That’s because the level of hormones the body makes can be different from one cycle to the next, and this affects the amount and length of bleeding.

What Is The Follicular Phase

The follicular phase is the phase that begins with the first day of menses . During the early part of this phase, the pituitary gland increases the release of follicle-stimulating hormone and luteinizing hormone . FSH stimulates the growth of numerous follicles in the ovary as well as the release of estrogen from the ovary. The estrogen causes the thickening of the endometrium. Generally, only one of the follicles matures and gets to release the ovum contained within. LH is secreted in a sudden burst mid-cycle and stimulates the release of the ovum from the mature follicle in the ovary.

Your cycle begins on the first day you have regular bleeding. Spotting doesnt count. For example, Cycle Day 1 is the first day of your period Cycle Day 2 is the second day of your period, Cycle Day 3 is the third day of your menstrual flow, and so forth.

As an example, create sample menstrual calendar for the month of January. Lets say you had spotting on January 3rd, but you didnt have regular bleeding until the next day. The first day of your menstrual period would be January 4th. The first day of your period is also called Cycle Day 1.

Now, create sample menstrual calendar for the month of February. Lets pretend your period started on the 2nd. In January, your period started on Jan. 4th and in February it started on the 2nd.

When your health care provider asks you: When was your last period? The answer is the date of the first day of your last period . Ex.= February 2nd.

To figure out how long your cycle is, start at cycle day 1 of your last menstrual cycle and begin counting . The length= the last cycle day before you started bleeding again. For example According to the January and February calendars, the cycle length would be 30 days, meaning your period comes on average, every 30 days. However, keep in mind that your cycle may vary in length.

How To Track Your Menstrual Cycle

There are multiple ways to track a menstrual cycle and different tools to help understand that information. Heres what to know:


The most basic way to track your cycles is to note the beginning and ending date of each period and how heavy or light it is. Keeping up with that information can help you pinpoint any changes or irregularities in cycle length.


A step beyond keeping track of the period is monitoring vaginal secretions, or cervical mucus, during a cycle.

A telltale sign of ovulation is mucus, Urrutia says. Before ovulation, estrogen levels are very high, and there are receptors in the cervix that bind to the estrogen and create a different type of mucus, very wet and slippery. This usually happens three to seven days leading up to ovulation.

After ovulation, progesterone levels rise, producing a thicker mucus, which may lead to women observing no mucus at all. About two weeks later, you should get your period.

Basal Body Temperature

Basal body temperature is the bodys lowest temperature during sleep. Its usually taken right after waking up in the morning, using a digital oral thermometer or one specially designed to measure basal body temperature.

Taking this temperature every day is used to track changes in progesterone, Urrutia says.

Basal body temperature can be affected by things like unusual sleep patterns or drinking too much alcohol the night before.


Combined Hormonal Birth Control

Combined hormonal birth controlâlike the pill, the vaginal ring, or the patchârelease synthetic forms of estrogen and progesterone into your body . When taken as directed, the hormones in these types of birth control prevent your ovaries from preparing and releasing eggs . This stops your bodyâs usual hormonal cycling rhythm, allowing the birth control to regulate the growth and shedding of your uterine lining .

The bleeding you experience on combined hormonal birth control is not a real period. It is called withdrawal bleeding because it is caused by the withdrawal of hormones during the placebo pills or during the week you donât use your pills, patch, or ring.

Tracking Menstruation: How It Helps Your Reproductive Health

Knowing your cycle length is beneficial for a number of reasons. For women trying to conceive, understanding the timing of your cycle is valuable for determining the time you are most likely to get pregnant.

Women are considered fertile when an egg has been released from the ovaries and is able to be joined by a mans sperm. Because of how long both the egg and the sperm survive inside a womans fallopian tubes, the American College of Obstetricians and Gynecology says you can become pregnant if you have sex anywhere from five days before ovulation until one day after.

Generally, ovulation is said to occur about 14 days before the start of your next menstrual period. But every woman and every cycle are different. Knowing when you might really be ovulating and having intercourse around that time can enhance your odds of getting pregnant.

When Are You Most Fertile

“Theoretically, there’s only a short time when women can get pregnant, and that is the time around ovulation,” says Belfield.

It’s difficult to pinpoint exactly when ovulation happens but in most women, it happens around 10 to 16 days before the next period.

“It’s not accurate to say that all women are fertile on day 14 of the menstrual cycle,” says Belfield. This might be true for women who have a regular, 28-day cycle, but it won’t apply to women whose cycles are shorter or longer.
