Written by HealthAnswers editorial team Medically reviewed by [HealthAnswers UK doctor review panel](https://healthanswers.co.uk/our-doctors/) Reviewed 3 July 2026 ## Quick answer What is miscarriage? Miscarriage is loss of pregnancy before 24 weeks — most common in first trimester, affecting about 1 in 8 confirmed pregnancies. Symptoms include vaginal bleeding and cramping — but bleeding in pregnancy is common and not always miscarriage. Early pregnancy unit assessment with scan confirms. Most miscarriages complete naturally; some need medical or surgical management. Emotional impact is significant — support available through GP and charities. Seek emergency care for heavy bleeding, severe pain, or fainting. ## Who is this page for?

Vaginal bleeding — light to heavy — cramping lower abdominal pain, passing tissue or clots, loss of pregnancy symptoms sometimes. Some miscarriages discovered on scan without bleeding — missed miscarriage. Ectopic pregnancy causes similar early symptoms — must be excluded with scan. What causes miscarriage? Most first trimester losses due to random chromosomal abnormalities in embryo — not preventable. Less commonly — uterine abnormalities, antiphospholipid syndrome, thyroid disease, uncontrolled diabetes, infection. Advanced maternal/paternal age increases risk slightly. Previous miscarriage increases recurrence modestly. How is miscarriage managed? Expectant — wait for natural completion if safe. Medical — misoprostol tablets to expedite. Surgical — MVA/ERPC vacuum aspiration under anaesthesia — if incomplete, infected, or preferred. Early pregnancy unit advises best option. Rhesus negative women need anti-D injection after certain events. How long after miscarriage can I try again? Physically — ovulation can return within 2 to 4 weeks — many advise waiting one period for dating next pregnancy though evidence allows trying when emotionally ready. No proof waiting improves next outcome unless molar pregnancy or ectopic treatment. When is recurrent miscarriage investigated? After 3 consecutive miscarriages (2 in some clinics if maternal age over 40 or no live birth) — tests include antiphospholipid antibodies, thyroid, uterine cavity imaging (hysteroscopy/3D ultrasound), parental karyotypes selected cases, thrombophilia screen debated. ## Sources - [NHS — Miscarriage](https://www.nhs.uk/conditions/miscarriage/) - [NICE — Ectopic pregnancy and miscarriage](https://www.nice.org.uk/guidance/ng126) - [Miscarriage Association](https://www.miscarriageassociation.org.uk/)
