Period Diaries and Hormonal Changes: Understanding Your Body
Every woman goes through a monthly cycle of hormonal changes that can greatly impact their physical, emotional, and mental well-being. This cycle is commonly referred to as the menstrual cycle and is often accompanied by a period or menstrual bleeding. Despite this being a natural and normal process, many women still feel a sense of discomfort, embarrassment, or confusion when it comes to their periods and the changes that happen in their bodies. In this blog post, we will delve into the topic of period diaries and hormonal changes, and help you understand your body better.
Understanding the Menstrual Cycle
The menstrual cycle is controlled by hormones that signal the body to prepare for pregnancy. This cycle typically lasts for 28 days but can vary from person to person. The first day of the cycle is marked by the first day of menstrual bleeding, also known as the period. The menstrual cycle is divided into four phases: the menstrual phase, follicular phase, ovulation phase, and luteal phase.
The Menstrual Phase: This phase starts on the first day of bleeding and lasts for about 5-7 days. During this phase, the body sheds the lining of the uterus, along with blood and tissue, which is what we refer to as the period.
The Follicular Phase: This phase begins after the period ends and lasts for about 7-10 days. During this phase, the body produces follicle-stimulating hormone (FSH), which stimulates the ovaries to produce and mature eggs.
The Ovulation Phase: This phase typically occurs around day 14 of the cycle and lasts for 3-4 days. During this phase, the body produces luteinizing hormone (LH), which triggers the release of a mature egg from the ovary. This is the most fertile phase of the menstrual cycle.
The Luteal Phase: This phase starts after ovulation and lasts for about 10-14 days. During this phase, the body produces progesterone, which thickens the lining of the uterus to prepare for a potential pregnancy. If pregnancy does not occur, the levels of progesterone and estrogen drop, triggering the start of a new menstrual cycle.
Hormonal Changes During the Menstrual Cycle
As mentioned earlier, the menstrual cycle is controlled by hormones, specifically estrogen and progesterone. These hormones fluctuate throughout the cycle, leading to physical, emotional, and mental changes in the body.

Estrogen: This hormone is responsible for the growth and development of female reproductive organs, as well as the regulation of the menstrual cycle. During the first half of the cycle, estrogen levels gradually rise, peaking just before ovulation. This can lead to feelings of happiness, energy, and increased libido.
Progesterone: This hormone is responsible for maintaining the lining of the uterus and preparing the body for pregnancy. During the second half of the cycle, progesterone levels increase, causing symptoms such as bloating, mood swings, and breast tenderness.
Hormonal changes during the menstrual cycle can also affect other areas of the body, such as the skin, hair, and digestive system. Understanding these changes can help you better manage and anticipate any discomfort or changes in your body.
Using a Period Diary
Keeping a period diary can be extremely helpful in tracking and understanding your menstrual cycle. It can also help you identify any irregularities or changes in your cycle that may need medical attention. A period diary should include details such as the start and end dates of your period, the type of flow, any physical or emotional symptoms, and any external factors that may have affected your cycle (such as stress or medication).
There are also various period tracking apps available that can make it easier to keep track of your cycle. These apps can also provide insights into your cycle and predict when your next period is due, making it easier to plan ahead.
Understanding Your Body’s Needs
Hormonal changes during the menstrual cycle can greatly impact your body’s needs. For example, during the follicular phase, your body may require more iron-rich foods to replenish the blood lost during the period. Similarly, during the luteal phase, your body may crave more fatty or sugary foods due to the drop in estrogen and progesterone levels.
It is important to listen to your body and give it what it needs during different phases of your cycle. This can also help alleviate any physical or emotional symptoms you may experience during this time.
Summarized
The menstrual cycle is a natural and normal process that is controlled by hormones and can greatly impact a woman’s physical, emotional, and mental well-being. Understanding the four phases of the cycle and the hormonal changes that occur can help women better manage and anticipate any discomfort or changes in their bodies. Keeping a period diary and understanding your body’s needs during different phases of the cycle can also be helpful in tracking your cycle and managing any symptoms.
