COVID-19 (coronavirus): restrictions are in place nationwide. Get advice to stop the spread 


Most miscarriages can't be prevented. Experts say most miscarriages happen because of a problem with the baby’s chromosomes. This means the pregnancy cannot develop properly.

You can do the following things to reduce your risk of miscarriage:


Wash hands carefully, especially:

  • before eating, drinking and preparing food
  • after going to the toilet, helping a child toilet or changing a baby's nappy


Wear a condom during sex if:

  • you or your partner have other partners
  • your male partner has any symptoms of a sexually transmitted infection (STI) - such as a rash or blisters on his penis or discharge from the tip of his penis.
