For such a long time I judged myself when I didn't feel the exact same day to day and when I had "bad" days as opposed to good days.
Fast forward to now, and I have realised it's NORMAL. We are cyclical beings. We are not meant to always feel exactly the same. Honour those changes and honour the different stages in your cycle.
I am by no means an expert but my hope is to empower you to start looking further into your cycle and getting in tune with your body.
