Struggling with Sleep during mid-luteal phase – Any Tips?

I’m 38 and about 9 days before my period (mid-luteal phase), and no matter how exhausted I feel, I just can’t sleep. I exercise regularly and take magnesium, a multivitamin, and ashwagandha, but nothing seems to help.

Any women here experience insomnia tied to their hormonal cycle? What actually works for you?
