Always heavy period, help!?

So, ever since I can remember, I've had heavy bleeding the first three days of my period and then the last 2 days are pretty chill. In the first 3 days, I stress... so much about leakage while I sleep. I even wear 2 full overnight pads with wings the whole day and while I sleep. (I wear one normal and one across the top going sideways, kinda like a T form.) I still will have leakage. What can I do to make it not so heavy? Any advice would be... Amazing. Lol.
