When a feeling comes before a thought

I can feel before I even open my eyes in the morning if I have PMT. There is a tightness in my belly and a lower vibration in my mind/body. Most mornings I wake happy and with a smile on my face and I have been tracking the mornings that I don’t and it is all around my cycle. On these days I find I’m sluggish in movement and lack motivation. Being in this lower vibration then leads to thoughts that don’t serve me. BUT I do believe the thoughts come through feeling low from the moment I wake up. Can you please speak to this?
