Irregular Menstrual Cycles - Understanding the Basics

For some people, cycles are predictable; for others, they can feel less consistent. This often leaves us with questions like:

• Why is my period later than usual?
• Are irregular cycles common?

• What lifestyle factors might be influencing my cycle?

This blog explores some of the elements that may influence cycle regularity and offers general wellbeing approaches that can help support menstrual health.

A regular cycle is generally considered to be between 28-35 days. Variations outside this range may be described as “irregular.” For some, this may mean cycles that are shorter or longer than average, or vary significantly from month to month.

Cycle patterns can be influenced by a variety of things, including:

• Stress: Ongoing stress can affect hormone balance and may contribute to cycle changes.
• Diet & Nutrition: Nutrients play an important role in supporting menstrual health and energy balance.
• Exercise: While movement is beneficial, excessive exercise combined with low energy intake can sometimes influence cycle length.
• Sleep: Consistent, good-quality sleep is important for hormone health and overall wellbeing.
• Life Stages: Puberty, post-pregnancy, breastfeeding, and perimenopause are all times when cycles can naturally shift.

If you notice your cycle feels irregular, there are steps you can take to support your general wellbeing:

• Balanced Nutrition: Aim for regular meals with whole foods that provide steady energy and help maintain healthy blood sugar balance.
• Stress Management: Incorporating yoga, meditation, or other calming practices can support nervous system health.
• Regular Movement: Moderate exercise supports circulation, energy, and hormone balance.
• Nutrients & Supplements: Certain nutrients are listed in Australia to support menstrual health. For example, Myo-Inositol supports a healthy menstrual cycle, reproductive health, preconception health, nervous system health, and healthy blood sugar balance.
• Professional Guidance: Everyone’s body is different. If you’re concerned about your cycles, always consult with your healthcare professional for personalised advice.

Cycle regularity can look different for everyone, and what’s “normal” varies. By focusing on lifestyle factors such as stress, sleep, nutrition, and exercise, many people can support healthy cycle patterns. Supplements like Myo-Inositol can also play a role in supporting menstrual cycle health and general wellbeing, but they should always be used as part of a holistic approach with guidance from a healthcare professional.
