I took medroxyprogesterone to induce a period ttc. I am on day 9 of my cycle for the last 6 days super heavy need to change every 2hrs is this normal?

Not normal. Heavy bleeding after Provera (medroxyprogesterone) is not uncommon but you need to be seen urgently to help curtail this amount of blood loss. Your gyn will have reviewed your hsg x ray to ensure the cavity of the uterus is free of polyps/fibroids and you may need blood clotting tests.
