Pregnancy after mmc

I am still waiting to either miscarry naturally or if I don't by Wednesday, book my d&c. But I have already been thinking about getting pregnant again. Not that I want to right away, but that I'm terrified. I'm so scared this is going to happen again. I hear so many stories of people having multiple miscarriages. I'm just afraid that there's something wrong with me and that somehow this is my fault and that it will keep happening. I don't know how to get over this fear. I know if I get another positive test I will just be anxious and worried about the pregnancy the whole time. Anyone have any advice or experiences they could share?
