Growth restriction is called late onset if it happens after week 32 of the pregnancy. It is often linked to other problems.

What are the symptoms of abnormal baby in pregnancy?

What if fetus is measuring small at 8 weeks?

Animal studies indicate that hypoxia affects a variety of developmental processes (eg, cell death)²⁹ and organ systems, which could result in various types of birth defects.

How soon after baby stops growing Do you miscarry?

If it is an incomplete miscarriage (where some but not all pregnancy tissue has passed) it will often happen within days, but for a missed miscarriage (where the fetus or embryo has stopped growing but no tissue has passed) it might take as long as three to four weeks.
