*Please note:

We all know that our menstrual cycles are rarely ‘neat’ and can vary from month to month in length. However, here and in the course - simply as a guide to get us started - we’ve used a menstrual cycle of 28 days with each phase being ‘neatly’ divided into about a week. Join the course to find out how long each of your phases are and how you experience each phase/inner season.
