Does late ovulation increase miscarriage?

Hi ladies. It’s CD21 for me and I’ve finally had a positive opk. Roughly a 30 day cycle. Early Miscarriage in early dec and my cycles have been pretty regular since. This is my first real month of <a href="">tracking ovulation</a>. My question is, is it safe to conceive so late on in a cycle? I’ve read that late ovulation imposes more of a risk with miscarriage, and I’ve even seen some parents convinced that their late ovulation is the causes of many birth defects like trusting 18, Down syndrome etc. The app says my period is due in 12 days, which would mean I would have such a short LH!
