Types of miscarriage

We still don’t understand why every miscarriage happens, but for those we do, a particular name for that miscarriage may be used.

The type of miscarriage you experience will give you more information about the causes in your case.

Early miscarriage

Is a miscarriage which happens in the first 12 weeks of pregnancy. Find out more about early miscarriage.

Late miscarriage 

Is a miscarriage  which happens after 12 weeks but before 24 weeks. Read more about late miscarriage.

Complete miscarriage

Is a loss that does not require clinical intervention for the pregnancy tissues to come away from your womb.

Incomplete miscarriage

Is a miscarriage that begins naturally, but not all the pregnancy tissues come away from the womb. Find out about the signs of an incomplete miscarriage.

Missed miscarriage (or silent miscarriage)

Is a miscarriage without any symptoms, so you may not realise that the baby has stopped growing or that anything is wrong until the loss is discovered at a routine scan. Read more about missed miscarriage.

Other medical descriptions that you may hear in connection to miscarriage are explained in our list of miscarriage terminology.

Chemical pregnancy

A chemical pregnancy is the term given to a pregnancy confirmed by a blood test or a home pregnancy test but not yet visible on an ultrasound scan (usually up until about 5 weeks of gestation). Learn more about chemical pregnancy.

Molar pregnancy (also called Hydatidiform mole pregnancy)

A molar pregnancy is a very rare complication - about 1 in 700 pregnancies in the UK is molar. It can happen when something goes wrong in the early stages of fertilisation that means that the baby and placenta don’t develop properly. Find out more about molar pregnancy.

Only 1 in 100 women suffer three or more miscarriages in a row. Doctors refer to this as recurrent miscarriage. Read more about recurrent miscarriage.

Ectopic pregnancy

Is a pregnancy where the baby develops outside the uterus, usually in one of the Fallopian tubes. Read about the signs and symptoms of an ectopic pregnancy.
