Feby is a colour-coded bracelet that works as a learning tool and calendar for the average woman's menstrual cycle.


Feby's unique colour arrangement acts as a guideline to what you can expect during different phases of your cycle, but it is by no means definitive. We are all unique yet we follow a general pattern. The pattern begins with red.

Start using Feby on the first day of your period. Make sure the knot is to the left hand side of the first red bead. Your cycle always starts with a red bead and ends with a black bead, flowing clockwise.

The first red bead is of utmost importance. It is the only truly definitive bead and all the others follow. It represents the first day of your period. Red symbolizes blood.

Each morning move the knot through one bead so it rests between two red beads. Now the knot is to the left of the second red bead. Just remember that the bead the knot is on the left of is the day of your cycle you are living that day. It's basically as though the beads are the days and YOU are the knot, moving through life one day at a time. 


Feby begins on the red bead beside the black bead. The bracelet flows clockwise through red, white, pink, white again and ending in black. Most women bleed between 3-7 days, with 5 being the average which is why there are 5 red beads. If you bleed a day or two more or less you are still considered within the average range and Feby will work for you. Feby is meant for the average woman whose menstrual cycle is 28 days.

The blood we shed is the thickened lining of the uterus that did not receive a fertilized egg. Periods can be light, moderate or heavy in terms of how much blood is shed and how quickly. 


White beads symbolize calm in regards to the impact on your body and emotions by your menstrual cycle. In the first half of the cycle, levels of estrogen (the "female hormone") start to rise. Estrogen plays an important role in keeping you healthy, especially by helping you to build strong bones and to help keep them strong as you age. Estrogen also makes the lining of the uterus (womb) grow and thicken. This lining of the womb is a place that will nourish the embryo if a pregnancy occurs. At the same time the lining of the womb is grown, an egg, or ovum, in one of the ovaries starts to mature. During this phase we usually feel no dramatic change in our disposition or physical well being as a result of our changing cycle. 


Pink beads suggest ovulation and fertility. The brighter the pink, the higher the probability you are ovulating. Most women will ovulate on a fuchsia (the brightest) bead.

At about day 14 of an average 28-day cycle, the egg leaves the ovary. This is called ovulation. After the egg has left the ovary, it travels through the fallopian tube to the uterus. Hormone levels rise and help prepare the uterine lining for pregnancy. A woman is most likely to get pregnant during the 3 days before or on the day of ovulation. Keep in mind. women with cycles that are shorter or longer than average may ovulate before or after day 14. During this phase we usually enjoy a positive disposition and physical well being. It is when hormone levels create a complex chemistry that increases our libido and pleasure of the senses.

There are various other methods one can use in conjunction with Feby to better determine ovulate. These include:

Lower abdominal discomfort.

Approximately 20 percent of women feel when they are ovulating; they notice mild aches or strong pain in their lower abdomen. This pain is called Mittelschmerz

A rise in body temperature.

After ovulation a woman's temperature can increase up to 1.6%. A basal body temperature thermometer is used to recognize this. The temperature spike indicates the production of progesterone, another hormone involved in the menstrual cycle and pregnancy. This method cannot predict exactly when you ovulated but just that you have.

Change in cervical mucus.

Your cervical mucus intensifies and changes texture as you progress through your cycle. This reflects the rising levels of estrogen in your body. When the mucus is abundant, slippery and clear with the texture resembling an egg white  you are considered most fertile.

Ovulation tests/Predictor kits

These work by detecting a hormone surge in your body that occurs directly prior to ovulation. These kits can be used at home to predict your most fertile time with great accuracy.



The second white grouping of beads represent the post-ovulatory stage. A woman becomes pregnant if the egg is fertilized by a man's sperm cell and attaches to the uterine wall. If the egg is not fertilized, it will break apart and be released from the body within 48 hours and hormone levels will drop. During this phase we feel little emotional or physical stress as associated with our cycle, hence the white beads.


Black beads indicate days shadowed by symptoms associated with premenstrual syndrome or PMS.  PMS is a group of symptoms linked to the menstrual cycle. PMS symptoms usually occur before your period starts (hence the PRE). The symptoms generally go away after you start bleeding. PMS can affect menstruating women of any age and the effect is different for each woman. For some people, PMS is just a monthly bother. For others, it may be so severe that it makes it hard to even get through the day. PMS usually goes away when your monthly periods stop, such as when you are pregnant or go through menopause. 

The causes of PMS are not completely clear, but several factors may be involved. Changes in hormones during the menstrual cycle seem to be an important cause. These changing hormones levels may affect some women more than others. Chemical changes in the brain may also be involved. Stress and emotional problems, such as depression, do not seem to cause PMS, but they may make it worse. Some other possible causes include;

  • Low levels of vitamins and minerals

  • Eating a lot of salty foods, which may cause you to retain fluid

  • Drinking alcohol and caffeine, which may alter your mood and energy level

PMS often includes both physical and emotional symptoms, such as:

  • Acne

  • Swollen or tender breasts

  • Feeling tired

  • Trouble sleeping

  • Upset stomach, bloating, constipation or diarrhea

  • Headache or backache

  • Appetite changes or food cravings

  • Joint or muscle pain

  • Trouble with concentration or memory

  • Tension, irritability, mood swings, or crying spells

  • Anxiety or depression

Symptoms vary from woman to woman, and even within the same woman during different months.

Not every woman suffers from symptoms associated with PMS but approximately 80% or more do at some point in their reproductive years. Consider yourself fortunate if you don't but do not assume it will always be that way; PMS symptoms seem to intensify as we age.

After the black days we will likely start the cycle all over again by getting our period. Feby works best for women with a 28 day cycle, however if you get your period on any black or red bead you are still considered average and Feby will assist you in developing a greater understanding of your cycle.

Please remember, that Feby is a guideline only to the average menstrual cycle.
