At the beginning of every year, I bust out my calendar, alongside a ruler, paper, and pen, and I draw another calendar for charting my menstrual cycle along with the moon cycle. Here is my 2020 version:
The calendar is on a 28 day cycle, which is why some days of the month overlap. Upon the first day of your cycle (the day your begin bleeding), circle that day and draw a line to cover all the days you bleed.
The comment section can be personalized to your own needs. I use it to keep track of PMS symptoms like cramps, acne, mood shifts, etc. I create columns of these symptoms and mark the presence of the symptom with an X. A larger X indicates severe symptoms, while a smaller x indicates mild symptoms.
I find it helpful to put all of this down on paper so I can notice patterns over time. At the end of the year, I compare this calendar with years past. I also get a kick out of comparing my cycle to the moon’s; a mysterious connection indeed!
Feel free to use this calendar and format as you see fit…
