I have read that it's common for women with MG to have flare-ups caused by hormonal shifts in their cycles, and that these flare-ups can be extreme. I'm so sorry you're going through this.

Maybe a gynecologist will encourage you to try a less radical treatment before considering a hysterectomy/oophorectomy, like a hormonal birth control pill that complete suppresses your cycle and keeps your hormone levels even.
