This prevents the baby from developing properly and can result in a miscarriage. They occur when the sperm or egg cell carries faulty chromosomes. In these cases, the heartbeat will sadly not reappear: Chromosomal AbnormalitiesĬhromosomal abnormalities are responsible for between 50 and 60 % of miscarriages.
