For those who have symptom reduction when estrogen is low, are there any good treatments?

I have less symptoms the first days of my period and had a remission first 6 months postpartum. If I'm understanding correctly I think I do better when my estrogen is low? Is there any way to mimic this or make my body have less estrogen? Granted I get migraines each period when the estrogen drops so idk if that would be an issue but im thinking it's the sudden drop that stimulates the migraine.

Is there a way to keep my estrogen low as a baseline? Is this even a viable option or healthy? Just some thoughts. Would appreciate any feedback. Thank you
