Menstrual cycle awareness is an essential part of understanding your monthly cycle and menstrual health.
Pay attention throughout the month, not just during your bleed.
Starting on day one - the first day of blood (not including spotting) take note of your desire and willingness to socialise, energy levels, self confidence, attention span, cramps and cervical fluids. Take note of anything and everything that changes for you, throughout the month.
Keep your charts together, put them side by side and watch patterns show themselves as you pay attention.
