Between the onset of puberty and the transition into menopause, menstruation is a common experience for many women. However, a surprising number are unaware of the intricate processes their bodies undergo each month. This gap in knowledge often stems from insufficient reproductive health education during formative years, but it’s never too late to familiarize yourself with the phases of the menstrual cycle or the ovulation process. Whether you’re aiming to conceive or simply want to monitor your cycle for health or personal reasons, grasping the nuances of your menstrual cycle is invaluable.

Thanks to modern technology, numerous apps and tools are available to help you track your period, anticipate ovulation, and plan around those days when “Aunt Flo” isn’t making a visit. While many people only consider their menstrual cycles when trying to become pregnant or dealing with issues, understanding your cycle can be an empowering experience. Our bodies are fascinating (and occasionally perplexing), and the more you learn about your specific cycle, the better equipped you will be to advocate for your health. Regardless of your life stage—whether you are preparing for conception, guiding your child through their first period, or managing early menopause—awareness of your body’s changes around your menstrual cycle is crucial.

Curious about the four phases of the menstrual cycle? Keep reading to explore this natural yet often mysterious process.

The Phases of the Menstrual Cycle

1. Follicular Phase
   As your period begins, a new phase unfolds. During the follicular phase, the pituitary gland secretes follicle-stimulating hormone (FSH), signaling the ovaries to prepare eggs for the upcoming month. Each month, the ovaries generate 5 to 20 small sacs called follicles, where eggs mature. These follicles produce estrogen, prompting the endometrium to thicken in anticipation of a fertilized egg. This phase typically lasts around 16 days, though individual variations exist.
2. Ovulation Phase
   For those trying to conceive, ovulation is often the most significant phase. This is when an egg is released from the ovary. Before this occurs, the body generates luteinizing hormone (LH), instructing the ovaries to release the matured egg. Each month, the egg travels through the fallopian tube to the uterus, where it awaits potential fertilization. In a typical 28-day cycle, ovulation usually happens around day 14, and if not fertilized, the egg dissolves within about two days. During ovulation, you may notice increased clear vaginal discharge and a slight rise in basal body temperature.
3. Luteal Phase
   The follicle that housed the egg before ovulation transforms into the corpus luteum during the luteal phase. This structure releases hormones like progesterone and estrogen, which maintain the uterine lining for a potential pregnancy. If fertilization does not occur, the corpus luteum diminishes and is reabsorbed by the body. This process triggers a decrease in estrogen and progesterone, leading to the start of menstruation and the shedding of the uterine lining. This phase is often associated with PMS symptoms like headaches, bloating, cramping, sleep disturbances, breast tenderness, and mood swings.
4. Menstruation Phase
   Finally, we arrive at the phase you are likely most familiar with: menstruation. During this time, the body expels the uterine lining, including blood and fluids. Typically, this phase lasts 3 to 7 days, though duration can vary. It can come with its own set of uncomfortable symptoms, such as cramps, back pain, and irritability. Interestingly, on day one of your period, your body begins the entire cycle anew with the follicular phase. While ovulation and menstruation often receive the most attention, each stage of the menstrual cycle is unique and deserving of understanding. The more you comprehend the processes your body undergoes, the better you can navigate your reproductive health.

What Causes Menstrual Cycle Changes?

Menstrual cycles can be sensitive to various factors, including:

• Birth Control: Many women use contraceptives to shorten or lighten periods; some options may even eliminate monthly cycles.
• Eating Disorders: Conditions such as anorexia or bulimia can lead to significant weight loss, resulting in irregular or absent periods.
• Stress: Elevated cortisol levels during stress can disrupt your cycle, leading to irregularities.
• Breastfeeding: Postpartum, menstrual cycles may become irregular. While breastfeeding, lighter periods or temporary cessation can occur due to the hormone prolactin. Once breastfeeding concludes, cycles typically return to normal.

Why Is My Menstrual Cycle Getting Longer?

Every cycle is different, but if yours tends to exceed the typical 28 days, it may be due to irregular ovulation. The hormone progesterone induces menstruation, but if the follicles do not ovulate, the necessary progesterone won’t release, resulting in a prolonged cycle as the uterine lining continues to build.
