As menstruating people, you would think that we would understand what a period is, the purpose of it, and all of the information it can give us. Unfortunately, we do not, and this is not okay. Our periods are more than a sign we are not pregnant, more than an inconvenience, more than something we have to just deal with. Understanding what they are and why we have them can provide us with significant information about our health. As Lara Briden, ND says, “it’s our monthly report card about our health.” 

 

In today’s blog, I discuss everything you should have learned in sixth grade, but didn’t, about what is normal. Part two and three of this blog series will talk about all the issues when you do not have a regular or healthy menstrual cycle, the various things that can affect your cycle like hormonal birth control, treatment considerations, and what alternative options are available. 

 

Starting from the beginning: menarche. 

 

In December of 2015, ACOG released a committee option paper titled “Menstruation in girls and adolescents: Using the menstrual cycle as a vital sign.This. Is. Huge. It is so important, first to know what is normal, and what is normal varies depending on which cycle of life we are in. For example, when you first start menstruating, cycle length can be longer than in your adult years because your hypothalamic-pituitary-ovarian axis (HPA axis) is just establishing itself and hormones fluctuate. You may have a cycle that is anywhere between 21 and 45; whereas longer than 35 days in an adult is typically abnormal. If you ask an adult figure in your life, who may not understand the menstrual cycle because they weren’t educated either, they may think something is wrong, take you to the doctor (probably your primary care physician) and you may be placed on hormonal birth control to ‘regulate’ your cycle. NO! This. Is. Normal! 

 

Typically, normal menarche (the start of menstruation) begins on average at the age of 12-13 years old in well-nourished populations and in developed countries. Changes to this norm could be due to environmental factors, socioeconomic conditions, nutrition, and access to preventive health care. Menarche typically begins two to three years after ‘thelarche’ which is the development of breast buds which can be as early as age eight; and in most this occurs menarche begins by the age of 15 (ACOG, 2015). 

 

Your menstrual cycle takes about three years to really establish itself. Cycles typically are 21 to 35, although they can fall out of that range and still be normal, and most menstruate (bleed) for about two to seven days (ACOG, 2015). As adults, normal menstrual cycles are between 21-35 days. The amount of flow can vary, but typical blood loss is 30 mL. Blood loss more than 80 mL is considered chronic blood loss and is associated with anemia. 

 

How to measure your blood loss in real life. Dr. Lara Briden gives a great example in her book “The period repair manual” where she presents how to count your menstrual products. 

 

Counting menstrual products:

1 soaked regular tampon or pad = 5 mL (1 tsp)

1 soaked super tampon/pad = 10 mL (2 tsp)

50 mL blood loss = 10 soaked regular product or 5 soaked super products

*These are the total products used, not each day

 

Recap: what is abnormal? 

  • Adolescent girls should be evaluated if they go longer than three months (90 days) between periods. 
  • Bleeding for more than seven days
  • Changing menstrual products every one to two hours
  • Changing pads during the night

 

What is a period?

Often, the terms periods and cycles are used in the wrong context. Periods are the time we are bleeding (menses) and our menstrual cycle is the entire time we are bleeding and not bleeding, until the cycle repeats itself. Periods are called periods because it comes periodically at approximately monthly intervals. The first day of actual bleeding (not spotting) is day one of your menstrual cycle. Most people bleed on average three to five days. 

 

The phases of your cycle

A cycle is classified as day one of heavy bleeding to day one of your next period. Heavy bleeding is not the light spotting or ‘brownish’ discharge that may occur right before your period actually starts, this spotting is actually left-overs from the previous cycle. 28days is the average cycle for adults, but can be anywhere from 21 to 35 days and still be normal. 

 

The Follicular Phase: The first phase of your cycle is called the follicular phase which is approximately two weeks. In this phase, your ovarian follicles are entering the final stages of development, and there is one dominant follicle that will release an egg at ovulation. Typically this phase can last anywhere from seven to 21 days (Briden, 2018). 

 

In this phase a few of your follicles enter their final stages, although they began this process long before. Dr. Briden points out, it takes about one hundred days (~three months) for an ovarian follicle to reach maturation. During this phase, a hormone from your pituitary gland is releasing follicle-stimulating hormone (FSH) and luteinizing hormone (LH) which help them to reach ovulation and produces the sex hormone estradiol (Briden, 2018). Estradiol is the primary estrogen in premenopausal women, and plays a significant role in your health and is involved with mood, bone health, and insulin resistance. It helps to promote the growth of the uterine lining in anticipation of pregnancy. During this time where estradiol dominates, you may see a change in your cervical mucus in your vaginal discharge. This type of mucus tends to be creamy, wet, and slippery (Briden, 2018). Your vaginal discharge is a combination of this mucus, shed cells from your vaginal wall, and healthy bacteria (Briden, 2018). 

 

Ovulation is the next phase and lasts one day. The dominant follicle releases an egg that is ready to be fertilized or be released along with the endometrium during your next period. 

 

The luteal phase is the last phase and lasts between 10-16 days. This stage is very important and it only happens if you ovulate. Only then, will you also produce progesterone. What happens in this phase is that the follicle that released the egg begins to change into a gland that starts to secrete progesterone. Progesterone is sometimes referred to as “the pregnancy hormone” that dominates during pregnancy. If you are not pregnant this hormone still plays a vital role in your health such as balancing estrogen, breast cancer prevention, and increasing your body temperature (which is the basis of measuring your basal temperature in the fertility awareness method). Other benefits of progesterone are reducing inflammation, promoting sleep, and calming the nervous system (Briden, 2018). 

 

Why ovulation is important 

Ovulation is important because it is the event that the follicle has prepared 100 days for. This means that something that was ongoing with your health three months prior may show up now (Briden, 2018). This could be inflammation, poor nutrition, stress, etc. The corpus luteum, which turns into the gland that secretes progesterone has to live a healthy life so that it can not only release the egg, but then shift into essentially a completely different structure with its own blood supply in just a short amount of time (Briden, 2018). If it is unhealthy, it may not release an egg at all or it may only produce a small amount of progesterone, which could cause some problems as we will discuss in a later blog post.  

 

The fate of the egg: Period or Pregnancy

In healthy menstrual cycles, your fertile time is the three (sometimes five) days before you ovulate and the day of ovulation. The reason for this is because the cervical mucus you should see around the time of ovulation, also known as the fertile mucus, was stimulated by the estradiol from the follicle that just released that egg. It is the perfect environment for sperm, and sperm can survive for a few days, but the egg can only survive for twenty-four hours. Remember, this is in reference to normal, healthy menstrual cycles only. Your fertility window can change if your cycle is abnormal and you do not follow a normal menstrual pattern. It may also change if there has been significant stressors (perceived stress is important, diet, exercise, illness etc. can also affect this normal pattern). After the egg is released, its fate is either pregnancy or to be released out of your body during your period. This cycle repeats itself every month until you begin to approach menopause, get pregnant, or have an underlying health condition.
