Irregular menstrual cycles can be a source of concern for many women, and understanding the underlying causes is essential for addressing any potential health issues. Based on your description, it seems you are experiencing some unusual symptoms leading up to your menstrual cycle, including breast tenderness, increased hunger, body aches, and irregular bleeding patterns. Let's break down these symptoms and explore possible causes.

Firstly, the symptoms you experience before your period, such as breast tenderness and body aches, are commonly associated with premenstrual syndrome (PMS). PMS can manifest in various ways, including mood swings, bloating, and physical discomfort. However, the irregular bleeding you described—spotting a week before your expected period and then having a lighter flow—could indicate a few different things.

One possibility is hormonal fluctuations. Hormones such as estrogen and progesterone play a crucial role in regulating the menstrual cycle. Changes in your environment, stress levels, diet, and lifestyle can all impact hormone levels, leading to irregular cycles. For instance, if you've recently changed your routine or experienced stress, this could contribute to the irregular bleeding and changes in your cycle length.

Another potential cause of irregular bleeding is the presence of anovulation, where the ovaries do not release an egg during a menstrual cycle. This can lead to irregular periods and spotting. Anovulation can be influenced by various factors, including stress, significant weight changes, or underlying health conditions such as polycystic ovary syndrome (PCOS).

Additionally, conditions such as uterine fibroids or polyps can cause abnormal bleeding patterns. These are non-cancerous growths in the uterus that can lead to heavier or irregular bleeding. Endometriosis, a condition where tissue similar to the lining of the uterus grows outside of it, can also cause irregular bleeding and pain.

Given that you mentioned your menstrual cycle has varied between 34 to 50 days, this irregularity can be concerning. While some variation is normal, consistently long cycles or significant changes in your cycle pattern may warrant further investigation. It's essential to consult with a healthcare provider who can perform a thorough evaluation, including a physical examination and possibly imaging studies or blood tests to assess hormone levels.

In summary, while some irregularities in menstrual cycles can be normal, especially in response to lifestyle changes or stress, persistent irregularities or unusual bleeding patterns should be evaluated by a healthcare professional. They can help determine if there is an underlying condition that needs to be addressed and provide guidance on managing your symptoms effectively. Keeping track of your menstrual cycle, symptoms, and any other changes in your health can also be beneficial when discussing your concerns with your doctor.
