Pregnancy and miscarriage

Patient: Hi, I had a miscarriage in February-March. I went to the hospital and found out I was in midst of a miscarriage around 4 weeks. I already have a son from previous relationship. My husband really wants a baby. I was wondering if I needed a D&C, because I haven’t gotten one? also, Could it be preventing me getting pregnant now because I haven’t gotten a D&C?

Symptoms: Miscarriage.
