Why am I so tired 3 days before my period?

Feeling tired and low on energy is a common complaint for many women leading up to their menstrual cycle. Have you ever wondered why you experience fatigue and lethargy a few days before your period? Well, fret not, because there is a scientific reason behind it. In this blog post, we will explore the phenomenon of feeling tired three days before your period and understand the changes that occur in your body during this time. We will also discuss various strategies to manage and reduce fatigue, so you can feel your best even during this phase of your menstrual cycle.

Overview of the menstrual cycle

To understand why you might feel tired before your period, it’s essential to have a basic understanding of the menstrual cycle. The menstrual cycle typically lasts around 28 days and involves various hormonal changes. These hormonal fluctuations are responsible for regulating your menstrual cycle and preparing your body for a potential pregnancy.

The two main hormones involved in the menstrual cycle are estrogen and progesterone. Estrogen is produced primarily during the first half of the cycle, leading up to ovulation. It plays a crucial role in regulating your mood, energy levels, and overall well-being. On the other hand, progesterone levels start to rise after ovulation and peak right before your period.

Changes in hormone levels before menstruation

Around three days before your period, estrogen levels tend to decrease significantly. This decrease in estrogen can have a direct impact on your energy levels and mood. Some women may experience fatigue and lethargy as a result of this hormonal shift. The exact reasons for this fatigue are not entirely understood, but it is believed that the changes in brain chemistry and neurotransmitters influenced by estrogen play a role in how you feel during this phase of your cycle.

In contrast, progesterone levels start to rise during the same time. While progesterone is essential for maintaining pregnancy, high levels of progesterone can also contribute to feelings of fatigue and lethargy. Additionally, progesterone can have an impact on your sleep patterns, making it harder to get a restful night’s sleep.

Other factors contributing to fatigue during this time

In addition to hormonal changes, there are several other factors that can contribute to fatigue before your period. One common factor is the presence of premenstrual symptoms such as abdominal pain, bloating, and headaches. These symptoms can cause discomfort and affect your sleep quality, ultimately leading to feelings of tiredness.

Furthermore, heavy menstrual bleeding can lead to iron deficiency and anemia, which can exacerbate fatigue. Anemia occurs when your body doesn’t have enough healthy red blood cells to transport oxygen efficiently, leading to fatigue and weakness.

Psychological and emotional factors can also play a role in how you feel before your period. Stress, anxiety, and mood swings commonly experienced during this time can contribute to feelings of exhaustion. It’s important to consider both the physical and emotional aspects of your well-being when addressing period-related fatigue.

Managing and reducing fatigue before menstruation

While it’s normal to feel tired before your period, there are several strategies that can help manage and reduce fatigue during this time. Let’s explore some of these strategies:

Lifestyle changes

Regular exercise and physical activity can help boost your energy levels. Engaging in activities like walking, yoga, or swimming can increase blood flow, release endorphins, and improve your overall well-being. It’s important to strike a balance between work and rest during this phase of your cycle. Make sure to prioritize self-care and allow yourself to rest when needed.

Dietary considerations

Eating a well-balanced diet rich in nutrients can support your energy levels. Include foods that are high in iron, such as leafy green vegetables, lean meats, and legumes, to prevent iron deficiency. Avoid excessive consumption of caffeine and sugar, as they can lead to energy crashes and affect your sleep quality.

Over-the-counter remedies and supplements

If you are experiencing anemia symptoms, your healthcare provider may recommend iron supplements to help boost your iron levels. Additionally, there are various herbal remedies and supplements available that can help manage menstrual symptoms and support your overall well-being. However, it’s important to consult with your healthcare provider before starting any new supplements.

Seeking medical advice and support

If your fatigue and symptoms persist or significantly impact your daily life, it’s essential to seek medical advice. Your healthcare provider can help determine if there are any underlying health issues contributing to your fatigue and provide appropriate treatment or recommendations.

Coping strategies for dealing with fatigue and low energy levels

In addition to the strategies mentioned above, practicing self-care and stress management techniques can greatly help in coping with fatigue during this time. Make sure to prioritize relaxation and engage in activities that promote rejuvenation and well-being. Whether it’s taking a warm bath, practicing meditation or deep breathing exercises, finding what works for you can make a significant difference in managing your fatigue.


Experiencing fatigue and low energy levels a few days before your period is a common occurrence for many women. The decrease in estrogen levels and the rise in progesterone levels during this phase of your menstrual cycle can contribute to these feelings of tiredness. However, by making lifestyle changes, managing your diet, exploring over-the-counter remedies and supplements, and seeking medical advice when needed, you can effectively manage and reduce fatigue during this time. Remember to listen to your body, prioritize self-care, and seek professional help if your symptoms persist or worsen. By understanding and addressing period-related fatigue, you can take control of your well-being and feel empowered throughout your menstrual cycle.
