How To Treat Prolonged Bleeding During Periods And Cramps?

Hi, I started minesse on the first day of my period, but i continued bleeding after the fifth day of my period. I experienced cramps every morning since my period stop, followed by bleeding, and this cramp would occur three times a day before i would bleed. In addition i had lost all sexual sensation during sex, which lead me to stopping the pill. Its been 4 days since I've stopped the pill and I'm still bleeding. Is there any prescription medication I can take to stop the bleeding?
