What are the signs of the Period Coming?

The menstrual cycle can sometimes be associated with certain signs and symptoms that women may experience before and throughout its different phases. These signs can vary from person to person and might be influenced by hormonal fluctuations and individual differences. Here are some common signs you can experience before your menstrual cycle begins; 

  1. Menstrual Cramps
  2. Acne Prone Skin
  3. Tender Breasts
  4. Bloated Feeling
  5. Mood Swings
  6. Dry Discharge
  7. Feeling Tired

Tracking these early signs can help some women anticipate the arrival of their period and plan accordingly. 

Menstrual Cramps

Menstrual cramps, also known as dysmenorrhea, are a common premenstrual feature experienced by many women. These cramps typically occur a few days before or during the menstrual period. The severity of cramps can vary, ranging from mild discomfort to more intense pain. Some women may find relief through over-the-counter pain medications, applying heat to the lower abdomen, or practising relaxation techniques.

Acne Prone Skin

Hormonal fluctuations, particularly increased levels of androgens (male hormones), can stimulate the sebaceous glands in the skin to produce more oil. This excess oil can clog pores, leading to acne breakouts. Acne-prone skin is common during the premenstrual phase due to these hormonal changes. Maintaining a consistent skincare routine and avoiding harsh products can help manage acne. In some cases, topical or oral medications prescribed by a dermatologist may be necessary.

Tender Breasts

As the menstrual cycle progresses towards menstruation, estrogen and progesterone levels fluctuate. These hormonal changes can cause the breast tissue to become more sensitive and swollen, leading to breast tenderness. Wearing a supportive bra and avoiding excessive caffeine intake can help alleviate discomfort.

Bloated Feeling

Hormonal changes, particularly an increase in progesterone levels, can lead to water retention in the body. This can result in a bloated or full feeling in the abdomen, often accompanied by mild weight gain. Staying hydrated, consuming a balanced diet, and reducing sodium intake may help reduce bloating.

Mood Swings

Hormonal fluctuations particularly changes in estrogen and serotonin levels, can impact neurotransmitters in the brain, leading to mood swings and emotional changes. Some women may experience irritability, sadness, anxiety, or heightened sensitivity during the premenstrual phase. Engaging in regular physical activity, practising relaxation techniques, and getting enough sleep may help manage mood swings.

Dry Discharge

As the menstrual cycle progresses towards menstruation, hormonal changes can affect vaginal discharge. Some women may notice a decrease in vaginal secretions, resulting in drier conditions. This is normal and is usually not a cause for concern. However, if itching, irritation, or unusual odour accompanies the dryness, it's essential to consult a healthcare provider.

Feeling Tired

The combination of hormonal fluctuations, potential discomfort from cramps or bloating, and emotional changes can contribute to feelings of fatigue or tiredness before menstruation. Engaging in regular physical activity, maintaining a balanced diet, and getting enough rest can help combat fatigue during this time.

It's important to remember that these premenstrual features can vary in intensity and duration among women. Utilizing a period cycle calculator not only enables you to predict future period dates

but also calculate period while explaining when you might experience these symptoms.
