Understanding Your Menstrual Cycle Phases and Hormonal Changes

Updated: Oct 18

Do you feel fully connected to your menstrual cycle phases and understand how the phases should unfold? Perhaps you've noticed some irregular symptoms or a sudden change in the length of your cycle. If so, you're not alone, and you've come to the right place. 


In this article, we’ll explore the menstrual cycle phases from a Western medicine perspective, helping you gain the knowledge to support your body in the way it’s naturally designed.


Why This Matters


Caring for your menstrual health is an investment in your overall well-being, especially if you plan to conceive. Balancing the proper levels of activity, rest, and nutrition is fundamental to regulating all aspects of health, including your menstrual cycle. But why have we drifted away from understanding and caring for our menstrual health?


Here’s My Perspective


My grandmother had a deep understanding of women’s health, but because she lived far away, I missed out on those precious conversations about periods. Over time, our society has moved away from multi-generational homes where such knowledge was passed down through stories shared in the evening. 


Now, we often find ourselves looking at separate screens instead of connecting. Furthermore, sanitary product adverts—especially those for tampons—tend to portray periods as something to ignore or hide, adding to the stigma and the already existing lack of menstrual health education.


Contraceptive pills, implants, and coils often disrupt our menstrual cycles. And let’s be honest: We usually don’t pay much attention to menstrual health until we decide to get pregnant. That’s unfortunate because a healthy menstrual cycle is key to balanced hormones, regular ovulation, and freedom from PMS.


Before I jump in, I want to keep this conversation focused and manageable so we’ll concentrate primarily on the physiological aspects of the menstrual cycle.


Understanding the Follicular Phase for Regular Periods Naturally


A normal menstrual flow should last 3-5 days. Ideally, you’ll experience a consistent flow from beginning to end without any spotting. The colour and consistency of the blood during this phase are essential indicators of good health. A healthy crimson red without clots signifies that all is well and supports the goal of maintaining regular periods naturally.

The menstrual cycle phases mark the shedding of the endometrial lining of the uterus. During this time, blood vessels constrict, leading to the shedding of the uterine lining, which results in menstrual bleeding. 


As menstruation subsides, the pituitary gland releases follicle-stimulating hormone (FSH), which stimulates the development of ovarian follicles—an essential process for achieving regular periods naturally.


The first phase, known as the Follicular Phase, spans approximately 12-14 days, starting with your period and ending with ovulation. This phase is characterised by physiological and anatomical changes driven by hormonal fluctuations, primarily oestrogen and FSH, produced by the pituitary gland and the ovaries. 


During the Follicular Phase, the ovaries orchestrate the growth of follicles, and a new endometrium starts growing, preparing for potential implantation. These processes are vital to maintaining regular periods naturally, as the cervical mucus also undergoes changes that make it easier for sperm to survive.


Several ovarian follicles begin to mature in response to FSH. Each follicle contains an immature egg (oocyte). As follicles grow, they secrete increasing amounts of oestrogen, which stimulates the thickening and proliferation of the endometrial lining in the uterus. 


Typically, one dominant follicle emerges and continues to develop while the others regress. This dominant follicle secretes the highest levels of oestrogen, which is crucial for a healthy menstrual cycle and regular periods. The thickened endometrium provides an ideal environment for potentially implanting a fertilised egg.


Finally, the dominant follicle, which has been nurtured and developed during the Follicular Phase, ruptures, releasing the mature egg into the fallopian tube. This natural process ensures that your body is on track for regular periods naturally.


Increase Your Menstrual Cycle Awareness About Ovulation and the Luteal Phase


It's time to shift our thoughts onto ovulation, from viewing it as a singular event to appreciating it as a dynamic process seamlessly integrating into the broader spectrum of your menstrual cycle and overall life.

Ovulation doesn't occur in isolation; it is intricately linked to various factors influencing your well-being, such as hormones, sleep quality, nutrition, and stress. Embracing menstrual cycle awareness allows you to see ovulation as part of a continuous cycle that reflects your overall health.


Towards the end of the Follicular Phase lies your fertile window, spanning approximately five days, with ovulation lasting between 12 to 24 hours. 


Contrary to the common belief that ovulation occurs on day 14, only about 5% of women experience ovulation, according to this timeline. Understanding ovulation is an ongoing process. It connects your menstrual cycle phases and life experiences, which is essential for improving awareness of the menstrual cycle.


During ovulation and your menstrual cycle, a mature egg (oocyte) is released from the ovary into the fallopian tube, causing oestrogen levels to rise. This increase triggers a surge in luteinizing hormone (LH) from the anterior pituitary gland while the dominant ovarian follicle reaches its maximum size. 


The LH surge initiates the egg's final maturation and release from the mature ovarian follicle. Once released, the egg is captured by the fimbriae—finger-like projections at the end of the fallopian tube. The egg remains viable for fertilisation approximately 12-24 hours after ovulation, making this a critical time within your menstrual cycle.


What You Need to Know About the Luteal Phase 


After ovulation, the ruptured ovarian follicle transforms into a structure called the corpus luteum, a small gland that produces progesterone, vital for supporting a potential pregnancy. 


Ideally lasting 12 to 14 days, the luteal phase is crucial in maintaining a healthy menstrual cycle. During this phase, progesterone levels rise, prompting changes in the endometrium, which thickens to create a nourishing environment for a fertilised egg to implant.


Simultaneously, cervical mucus changes, becoming denser and less permeable, which helps block the cervical canal and protect the body from harmful bacteria or unnecessary sperm. A well-regulated and appropriately extended luteal phase is the cornerstone of reproductive health and the delicate balance of your menstrual cycle. Cultivating menstrual cycle awareness during this phase is essential for understanding your body's natural rhythms.


If fertilisation does not occur, the corpus luteum begins to degenerate toward the end of the luteal phase, leading to a decline in progesterone levels. However, if fertilisation and embryo implantation occur, the developing embryo produces human chorionic gonadotropin (hCG), which signals the corpus luteum to continue producing progesterone and oestrogen to support early pregnancy.


If pregnancy does not occur, the decreasing levels of progesterone trigger the breakdown of the corpus luteum, leading to the onset of menstruation and regular periods naturally and the beginning of a new menstrual cycle.


By maintaining menstrual cycle awareness, you can better understand how these processes relate to your overall reproductive health and how to get regular periods naturally.


Embracing Your Menstrual Cycle Phases for Better Health


Understanding your menstrual cycle phases isn't just about tracking dates or managing symptoms—it's about deepening your connection with your body and recognising the powerful rhythms that guide your health and well-being. 


As you cultivate menstrual cycle awareness, you gain insight into how your body functions and empower yourself to make informed choices that align with your natural rhythms.

Consider your menstrual cycle as a barometer of your overall health. Each phase offers a unique opportunity to listen to your body, address imbalances, and nurture your well-being. By paying attention to the subtle cues your body provides—from the consistency of your flow to the timing of your ovulation—you can create a more harmonious relationship with your cycle.


This awareness isn't just for the present moment; it's a lifelong skill that can guide you through different stages of life. Whether planning to conceive, managing stress, or simply aiming for regular periods naturally, the knowledge you've gained equips you to take proactive steps towards a healthier, more balanced life.


Remember, your menstrual health is a reflection of your overall health. By embracing your body's natural processes with understanding and care, you can improve your reproductive health and emotional and physical well-being. As you move forward, let this awareness be a source of strength, helping you to live in harmony with the beautiful, intricate cycles that make you who you are.
