If a midwife or doctor thinks you have a molar pregnancy, you'll have blood tests, an ultrasound scan and you'll need to see a specialist.

A molar pregnancy happens by chance. It may be more likely if you've had one before, you're a teenager or over 45, or you have an Asian background.

There are 2 types of molar pregnancy. Complete is where there's no sign of a baby, and partial is where there may be early signs of a baby.

If you've had a molar pregnancy, you can get support from your specialist team and charities like the Miscarriage Association.
