I Had A Dnc 7 Days Ago, After Bleeding Non

I had a dnc 7 days ago, after bleeding non stop for 8 months. The dr removed a large growth from my uterius opening. at first it was red light spotting then brown...now today very heavy red blood. I am having to wear 2 heavy flow pads at a time and change them hourly. I am still having bad cramps that feel like Charlie horses on my right side. is this normal? when will the bleeding stop?
