Some women will ovulate on time, others will have a slightly delayed cycle, and others won't ovulate at all. I don't think I ovulated after my first 7 miscarriages but I'm only going off the lack of remembered ovulation signs and the fact that I didn't get pregnant. I didn't actually track ov or anything. With my last miscarriage though, I did ovulate but it was a week later than normal if you counted my miscarriage as CD1. (If you consider that I ovulated exactly 2 weeks after my hpts went negative then I had a regular cycle.) So it could happen any time really. Just depends on your body.
