Hormones and fluency

Hormones and fluency Have any other women who stutter observed that they have improved fluency in correlation with different stages of their menstrual cycles? I have observed that around the ovulation phase my fluency is great and I feel happier and experience less social anxiety. Unfortunately is doesn’t last long. I wish I could feel like that all the time. Does anyone know if any studies have been done On hormonal effect on fluency ?
