misscarriage and ovulation after d and c

Jane
I had a d and c six days and only bled lightly for a couple of days. I was 12 week 5 days when I found out but the baby heart beat had stopped 11 weeks. I just want to be pregnant again. When did people ovulate after a d and c? 
I also have pcos and people said after pregnant it can make your cycle more regular. Has this happened to anyone?
