What Is the Most Common Cause of Miscarriage?

A chromosome problem can prevent an embryo from developing normally, so the pregnancy stops growing. This can happen without a known inherited condition and without an identifiable trigger. Miscarriage may also be linked with problems involving the uterus, hormones, infection, blood clotting, or other health conditions, but one loss does not establish a cause. Bleeding and cramps can occur in a viable pregnancy as well as during miscarriage, so symptoms alone cannot confirm what is happening.

Contact a pregnancy-care professional after bleeding, pain, or a change in pregnancy symptoms. A pregnancy test, examination, blood tests, and a Transvaginal Ultrasound may be used to assess location and development. If miscarriage is confirmed, options can include waiting for the tissue to pass, Medical Management of Miscarriage, or Surgical Management of Miscarriage. The suitable option depends on bleeding, infection risk, scan findings, symptoms, and your preferences. Emotional support is also part of care.

Seek urgent care for heavy bleeding, severe or one-sided abdominal pain, fainting, marked dizziness, shoulder-tip pain, fever, or feeling acutely unwell. These symptoms can indicate significant blood loss, infection, or a pregnancy outside the uterus and need prompt assessment. Do not drive yourself if you feel faint.

Can the scan confirm whether the pregnancy is developing or has passed? Do I need repeat blood tests or imaging? Which management option is appropriate for me? What bleeding, pain, or fever should prompt immediate help? When can I try for pregnancy again?
