Question: Why do missed miscarriages happen?

Chromosomal abnormalities in the fetus are the most often cause of missed miscarriages, since these abnormalities do not allow the pregnancy to develop. If a miscarriage has occurred early in pregnancy, you will often be able to expel the pregnancy tissue naturally.

How common are missed miscarriages?

Somewhere between 1-5% of pregnancies result in a missed miscarriage. It occurs when the baby has died or not developed but has not been physically miscarried. Unlike ‘normal’ miscarriages which often show symptoms of pain or bleeding, there aren’t usually any signs with a missed miscarriage.

When do most missed miscarriages happen?

The estimated figure is that miscarriage happens in around 1 in 4 recognised pregnancies, with 85% of those happening in the first trimester (weeks 1 to 12). A ‘late’ miscarriage, which is much less common, may occur between weeks 13 to 24 of pregnancy.

Why do I keep having early miscarriages?
