I'm the same I've been a year straight I'm on 6 months now every day is extremely heavy flow. I've been to at least 30 doctors in different states as well and have had every test done everything comes back completely normal. However o can say I was full vegan about a year ago and as long as I was I got my period normally every single month. So I'm making the translation back to being full fledge vegan now in order to regulate it. I know smoking (not cigs) helps a lot for me too as far as regulating it and slowing the flow) so eat healthier vegan if possible drink a lot of water every day and work out. You have to give your body at least a month before you'll start to see any changes
