Heavy period, more intense miscarriage?

If I have a heavy period usually will I bleed more and have a more painful miscarriage? I was going to request a d&c Wednesday when I go in for a follow up appointment but I have a feeling I'll miscarry before that. I started getting very light cramps last night. I was hoping for the d&c because I've read basically nothing but horror stories of women who have naturally miscarried. I am terrified.
