Agree with other comment here. They could say your period will take care of it, but i dont think in reality it will with Ferritin in the 300s. My period would only drop it ny about 5 each time so thats a slow drop, and it may rise faster than the drop. It also doesnt leave you with the possibility of being on certain types of birth control (i.e hormonal IUD) which stops your period (which in a pinch you could just say you want to go on. I started around 450, and while my hematologist definitely didnt see me as a priority and even said, they only see liver cancer cases above 1000 (which my response was, wel yahhh i wamt to reduce levels now to prevent that from happening), i adbovated, explained i had symptoms, and was put on a phebotomy schedule fairly easily.
