Fertility Awareness & How I Track My Cycle

by | Feb 6, 2019 | Health Articles, Women's Health

Fertility Awareness is a form of natural family planning & pregnancy prevention that through detecting day-to-day changes in our body. Learn all about it in today’s post.

Updated: May 2021

I’ve been interested in women’s health and reproduction for as long as I can remember. Growing up though I had little idea about how my menstrual cycle worked, what fertility entailed, or that there were other options for preventing pregnancy besides the birth control pill.

I took hormonal birth control for about 2 years as a teenager before deciding to come off of it. When I was in my early twenties I began learning more about my cycle and how to track it through Fertility Awareness Methods (FAMs).

I believe strongly in the importance of proper sex education and that’s what this post is all about: to educate you on ways that we can understand our cycle and bodies better. However, I am not suggesting that you stop doing what you’re doing. Choosing a birth control method is a very personal choice, they all have advantages and disadvantages, and there are many factors at play. Practicing Fertility Awareness Methods also requires diligence, consistency, and a thoroughness in detecting bodily signs. Not everybody is willing to or interested in taking this approach, and that is so perfectly okay! Do what’s right for you, because only you know your body and your needs best.

What Is Fertility Awareness?

Fertility Awareness is the practice of detecting day-to-day physiological changes in our body using multiple methods combined (Fertility Awareness Methods or FAMs) to help us to determine when we’re fertile or not so we can prevent or plan for pregnancy. Fertility Awareness is not the same as the rhythm method which I’ll talk more about later on in this post.

To understand how we can follow Fertility Awareness, and for general knowledge, let’s first go over the basics of a monthly cycle.

Understanding Your Cycle

A normal cycle lasts anywhere from 25-35 days, with a period that lasts between 3-7 days, and consists of 3 specific phases: follicular, ovulation, and luteal. These phases are controlled and orchestrated by a group of different hormones.

Follicular Phase: The first day of your period marks the start of the follicular phase. The dominant hormone is estrogen during this phase and it increases gradually over a number of days until ovulation occurs.

Ovulation: Immediately before ovulation, around the middle of our cycle (for a 28-day cycle this would be around day 14), we experience an “LH surge” where luteinizing hormone increases. With estrogen also at its highest our uterine lining thickens and we begin producing tons of a specific kind of cervical mucus to assist sperm entry. More on that later!

During ovulation an egg is released into the Fallopian tube and carried away to be fertilized or to die.

An egg at this time is only viable for approximately 24 hours. Yes, that’s right, an egg can only be fertilized for approximately 1 day in an entire cycle. HOWEVER, since sperm can survive in the vagina for about 5 days prior to ovulation, our “fertile window” can be around 7 days (typically about 25% of a standard cycle). 

Luteal Phase: After an egg is released from the ovary, its follicle develops into the corpus luteum which produces increasing amounts of progesterone. Once the corpus luteum dies and progesterone production decreases, cells in the uterine lining slough off (your period starts) which begins day 1 of a new cycle all over again. The luteal phase generally lasts about 14 days from the day you ovulated. This is a neat way to help you determine how long your cycle will be. If you ovulated earlier, say on day 12, then you can usually expect a shorter cycle of about 26 days. If you ovulate later, such as day 16, then you can expect your period to arrive around day 30.

Condoms / Barrier Methods

Before I get into the details of Fertility Awareness I want to emphasize the importance of barrier methods, such as condoms.

Because Fertility Awareness does not involve taking synthetic hormones to prevent ovulation, we experience our natural cycle with very fertile days and days when we’re a little uncertain, and using other forms of birth control are very important during those times. Condoms are what also protect us from STIs.

Fertility Awareness Methods

Alright, let’s dive in. Fertility Awarness involves utilizing few methods in conjunction with eachother, known as Fertility Awareness Methods (FAM). It’s important to remember that these methods are best used together for optimal tracking of your fertile window, not just one method by itself.

Basal Body Temperature (BBT)

Your basal body temperature is your body’s temperature at rest. Tracking this involves using a BBT thermometer to take your temperature immediately when you wake each morning before you get up or do anything else. Our basal body temperature fluctuates throughout our cycle due to hormonal changes that occur, and after you ovulate, there’s a specific small increase in temperature that helps us to determine ovulation.

I use the Daysy fertility tracker which is a comprehensive BBT thermometer. It logs your temperature for you each day by storing it in the device, along with the days of your period, and allows you to view the fluctuations when you connect it to the app. Each morning when I take my temperature it lights up either red, green, or yellow:

  • Red indicates that you’re fertile and should abstain from sex or use another form of birth control (i.e. condoms)
  • Green indicates that you’re not fertile.
  • Yellow indicates fluctuations or that it’s still learning your cycle. It takes a few months for Daysy to understand your data, so you see a lot of yellow lights when you first begin using it.

Cervical Mucus

Our cervical mucus is a particularly interesting visual tool that we can use to help us determine our level of fertility. I’ve tracked mine for many years and it’s become second-nature for me to take note of what type of fluid I’m producing on any given day.

Tracking your cervical mucus is as simple as noticing what’s on your underwear or what your fluid looks like when you wipe after going to the bathroom. It’s also helpful sometimes to physically feel it between your fingers.

The main types of cervical fluid to pay attention to are:

Dry: “dry days” occur when there’s little to no mucus production. This can occur right before your period, right after your period, and after ovulation, and indicates very low fertility.

Sticky: this type is gummy, tacky and typically occurs during the second half of your cycle after ovulation occurs or in the days following your period. It’s not hospitable to sperm and generally indicates low fertility levels.

Creamy: this fluid is very smooth (similar to lotion) and may be thin or watery. It tends to occur in the days leading up to our most fertile days but when we’re not quite most fertile yet.

Egg White” Consistency: this type of mucus is produced by our body when we’re most fertile as it allows sperm to travel much easier to your egg. This mucus occurs a few days leading up to and the day of ovulation. So, if you see it, know that you are very fertile at this time and most likely to get pregnant. This type of mucus is slippery, very stretchy, translucent in colour and has the consistency of raw egg white. With this type of mucus, you can pull it between your fingers and it will stretch.

Cervical Position

The position of our cervix (the opening of our uterus) changes angle throughout the month. When you’re fertile, your cervix becomes higher and softer and when you aren’t fertile, it’s firmer and lower. This can be felt with our fingers, but it can also be felt during intercourse and is experienced as different levels of comfort in certain positions throughout the month.

Cycle Tracking

I’ve been using an app called Clue for about 7 years now where I input the days of my period each month and any symptoms I’d like to track (cramps, breast tenderness, mood swings, etc.) This has been an invaluable tool for me to have an understanding of how long my cycles are on average, the symptoms I experience and when, and my approximate fertile window.

This method is also known as the Rhythm Method that I mentioned at the beginning of this post. I do not recommend using this method alone as it’s only an approximation of cycle data since there are many variables that influence our bodies (stress, illness, traveling). Only you are able to fully determine your other signs of fertility as outlined in this post. Please do not rely exclusively on a period tracking app for pregnancy prevention or planning). However, they’re still a fantastic way to understand our bodies better and they’re extremely useful when used in conjunction with the other methods.

    Thank you for this wonderful, comprehensive information, Meghan! I am looking to get off the pill and this is very helpful, as I have to be careful about pregnancy since I have a congenital heart condition. I’ve taken an NFP course at the advice of my doctor but this seems like a way to take the information I’ve learned there even further. Thank you for your amazing content!

    This is absolutely fascinating to me! I’ve always had issues with birth control and have been looking for other options. Do you recommend meeting with your gynecologist first before beginning to see if it is best for me?

    Hi Meghan,

    Thank you so much for your helpful post! I wanted to ask if you are comfortable trusting the Daysy even on green days, and partake in sex completely unprotected? I recently ordered one and have come off the hormonal pill from about 8 months of use due to bad side effects–so I feel as though my cycle will take some time to fully return (was never regular before). I guess I am asking if I can trust the daysy even on early green days? I would find comfort on hearing your opinion on this manner, thank you so much.

      Hey Stephanie! I track my cycle using a variety of methods (as listed in this post) so I’ve never relied on Daysy exclusively. We do use condoms and if I do have unprotected sex, I’ve only ever felt most comfortable right after and right before my period, far enough away from when I show signs of ovulation. I’ve been keeping track of my cycle and following Fertility Awareness for many years so it takes time to understand your body really well. I hope that helps! xx
