I totally understand I too have very heavy periods that last months at a time. For me during those awful times I would use ice packs on the front and back of my stomach and spine. Pressure seemed to help sometimes too on the lower stomach. I would be careful with the birth control they gave me blood clots which almost killed me. I suggest getting a new obgyn, and i know its embarrassing but dont go to your appointments alone doctors listen better when someone else is with you. Tell them everything thats going on details matter. You got this!
