Miscarriage: signs, assessment and what happens next

How common early losses are and why they occur

Early losses are common, but some are never identified. The 2024 Australasian guideline estimates that they affect about 12 to 15 per cent of clinically recognised pregnancies. Losses before that confirmation are additional. The figure depends on when and how pregnancies are detected and cannot predict your personal risk. ACCEPT guideline 2024

Chance chromosomal changes in pregnancy tissue often contribute to early loss. In a study of 2,928 available tissue samples, chromosomal abnormalities were found in 60.4 per cent of the 2,107 first-trimester losses. This result describes that study group, rather than explaining every individual loss. In many cases, the particular cause remains unknown. Shi and colleagues, 2025

A miscarriage does not show that you have done something wrong. Normal exercise, sex or a stressful day are not considered typical causes of early miscarriage. One loss does not establish permanent infertility either. With repeated losses, a focused assessment can look for factors that may be treatable. RCOG: causes and common concerns

Bleeding, reduced pregnancy symptoms or no signs

Bleeding, a pulling sensation in the lower abdomen and cramps can occur during a miscarriage. They can also have other causes, including bleeding from the cervix. Even clots or material that appears to be tissue cannot provide a reliable diagnosis at home. If the pregnancy had not been confirmed, it may be impossible afterwards to distinguish a heavier or delayed period from a very early loss. Other possible causes are discussed in bleeding during pregnancy.

A missed miscarriage may initially cause no pain or bleeding. Nausea or breast tenderness can persist because hormone levels do not drop immediately. These symptoms may also ease in a pregnancy that is developing normally. Neither having symptoms nor having none can establish on its own whether the pregnancy is viable. NHS: miscarriage

A positive home test followed by a negative result may occur with a very early loss. However, differences in test sensitivity, diluted urine and errors in reading the test can also affect results. How dark the test line looks is not a reliable way to monitor a pregnancy. If you have symptoms or uncertain results, medical follow-up at appropriate intervals is more useful than repeated comparisons of home tests.

When you need urgent help

If you are pregnant or could be pregnant, get bleeding or new pain assessed promptly. Do not wait for the next scheduled appointment if your condition clearly worsens. Seek immediate help through an emergency department or the local emergency number if you have:

• very heavy bleeding, for example a pad becoming soaked soon after you change it, especially with weakness;
• severe, persistent or one-sided lower abdominal pain;
• dizziness, fainting, collapse or serious circulatory problems;
• pain at the tip of the shoulder along with abdominal pain, bleeding or dizziness.

Fever, chills or foul-smelling discharge also require prompt medical assessment. Seek help immediately if you feel very unwell. An ectopic pregnancy or infection may cause similar symptoms. A small amount of visible blood does not exclude dangerous internal bleeding. RCOG: bleeding and pain in early pregnancy

In Germany, call 112 for emergency medical services in a life-threatening situation. For urgent but non-life-threatening concerns outside normal consultation hours, 116117 can help. If you have the severe warning signs above, contacting an out-of-hours service must not delay emergency care. 116117: out-of-hours care or emergency services?

How the diagnosis is established

Assessment considers your symptoms and medical history, usually together with a transvaginal ultrasound. It helps establish where the pregnancy is located and how it is developing. A transvaginal ultrasound does not increase the risk of miscarriage. RCOG: assessment for a suspected miscarriage

One scan may not give a clear answer very early in pregnancy. If ovulation happened later, less may be visible than expected from the date of the last period. Diagnosis must therefore not depend only on the calculated pregnancy week. Depending on the findings, the scan is repeated after an adequate interval, often no earlier than seven days and sometimes later. This helps prevent a viable pregnancy from being mistakenly diagnosed as a loss. NICE NG126: diagnosis

When a test is positive but no pregnancy has yet been reliably located inside or outside the uterus, the finding is called a pregnancy of unknown location. It may be a very early pregnancy within the uterus, a loss or an ectopic pregnancy. Blood hCG measurements taken about 48 hours apart are often interpreted alongside further ultrasound findings. A single hCG value cannot reliably determine either the location or viability. Falling hCG does not remove the need for the agreed follow-up.

Managing uncertainty while waiting

Moving between hope and fear can make waiting particularly difficult. A specific plan can help you manage uncertainty, even when it cannot resolve it immediately. Ask what is already known and what the next appointment is intended to clarify. If you are stable and have no warning signs, planned checks are an active part of care.

• What has the ultrasound shown, and which diagnoses are still possible?
• When should I have the next ultrasound or blood test?
• Which symptoms mean I should contact the team sooner, and who can I reach outside consultation hours?
• Can someone accompany me, and can I receive the findings in writing?

Treatment: waiting, medicines or a procedure

After the loss has been reliably confirmed, the next steps depend on bleeding, signs of infection, ultrasound findings and your preferences. If the uterus is already empty and there are no complications, further treatment may not be necessary. Otherwise, three approaches are often possible.

Waiting with medical support

The body may pass the tissue on its own. This can take days to weeks, and the timing is less predictable. Discuss pain relief, how to access help and when the next check will be. If the process does not start, symptoms persist or your wishes change, review the plan with the care team.

Medicines

Medicines help the tissue pass. For a missed miscarriage, mifepristone followed by misoprostol is often more effective than misoprostol alone. This does not apply to every form of miscarriage. Your care team will discuss the treatment plan and available medicines with you. Discuss bleeding, pain, possible side effects and follow-up before starting.

Surgical treatment

The tissue is usually removed by suction, also called suction curettage. This offers more predictable timing and may be needed for heavy bleeding, infection or when another treatment has not worked. Your distress and preferences also count. Discuss anaesthesia, benefits and risks such as bleeding, infection and, rarely, injury to the uterus.

If it is medically safe, you can take time to decide and can change your decision later. Choosing an option does not measure how you are coping with the loss. Medication regimens have been compared in research, including a randomised trial. Schreiber and colleagues, 2018; current guidance: NICE NG126: management.

Follow-up and pregnancy tests that remain positive

Agree on how completion of the miscarriage will be confirmed. Depending on the treatment, symptoms, ultrasound and sometimes hCG tests are relevant. The German-language guideline recommends ultrasound seven to 14 days after medical treatment. Other care pathways use a urine test at around three weeks. These are follow-up schedules, not instructions to put up with symptoms until the next appointment. DGGG, OEGGG and SGGG: early pregnancy loss guideline

hCG can remain detectable for a while after a loss. How soon the test becomes negative depends partly on the starting level and the course of the loss. A test that is still positive at the planned follow-up, continuing or increasing bleeding, pain or fever needs reassessment. Warning signs require attention even if the test is negative.

If you are RhD-negative, ask early about anti-D prophylaxis. This aims to prevent antibodies that could be relevant to future pregnancies. The German-language guideline takes the pregnancy week and treatment into account; recommendations after surgery differ from those for a very early spontaneous loss. Your clinician should clarify whether and when the injection is needed. International guidance varies. AWMF: early pregnancy loss, section on anti-D prophylaxis

The next few days: recovery, sex and periods

Bleeding, cramps and tiredness may be significant even after an early loss. Bleeding may continue for about one to two weeks after the tissue has passed, but should generally decrease. With expectant management, the process may take longer to begin. Worsening symptoms need further assessment. RCOG: recovery after miscarriage

Ease everyday demands where you can and arrange support, particularly if you are alone. Gentle activity can be resumed as you feel able. Pain or increasing bleeding is a reason to pause and seek medical advice if necessary.

The German-language guideline finds no evidence to support a blanket ban on tampons, menstrual cups, sex or physical activity after an uncomplicated early loss. Pads can help you judge how much you are bleeding. How you feel, along with individual advice for injury, infection or complications, should guide you. You do not have to resume something simply because it is medically possible. DGGG, OEGGG and SGGG: activity after early loss

The next period often comes after about four to eight weeks, though the cycle may take longer to settle. Ovulation can occur sooner, so pregnancy is possible before the first period. If you do not want another pregnancy yet, discuss contraception. Arrange a review if periods do not return or test results remain unclear. NHS: recovery after miscarriage

Support with daily life, work and saying goodbye

The next few days may feel more manageable with someone you trust available to talk, accompany you to appointments or help with shopping and childcare. You decide whom to tell and how much to explain. A midwife, pregnancy counselling service or grief support group may also help.

If physical or emotional symptoms leave you unable to work, discuss a medical certificate for sick leave. Since June 2025, Germany has also provided maternity protection periods after miscarriage from the 13th week of pregnancy. Eligibility and the duration depend partly on the week of pregnancy and employment circumstances. German Federal Family Portal: rules following miscarriage

You may want to keep an ultrasound picture, write a letter or create a small farewell ritual. You may prefer something else, or none of these. If you have questions about pregnancy tissue or burial, the hospital can explain local options. There is no prescribed way to grieve. BIÖG: grief following miscarriage or stillbirth

A future pregnancy and recurrent losses

After a single early miscarriage, a later pregnancy often has a successful outcome. There is no guarantee, but one loss does not justify assuming a permanently poor outlook. If the loss is medically complete and you feel physically and emotionally ready, an uncomplicated loss often does not require a fixed wait of several months. Certain findings or treatments may call for a different interval.

A follow-up discussion can help you plan when to contact the team after a new positive test, when an ultrasound would be useful and what to do if bleeding occurs again.

Before trying again, ask your doctor to review your medicines and folic acid needs. After a loss during IVF treatment, discuss when to plan the next embryo transfer with your treatment team. Advice after a spontaneous pregnancy cannot automatically be extended to IVF. NHS · PubMed

Repeated losses are a reason for a structured consultation. Some guidelines begin after two losses; others define recurrent miscarriage as three or more. Your history, age and type of losses influence when assessment is useful. It may look at the shape of the uterus, thyroid function, selected clotting or autoimmune factors and genetic questions where the history suggests a need. Not every specialised test improves care. RCOG: recurrent miscarriage

Grief has no set timetable

An early loss, or one discovered later, can be deeply upsetting. Some people initially feel numb; others feel sadness, anger or relief at finally knowing what has happened. Grief can become stronger after the appointments and physical symptoms are over. The stage of pregnancy does not dictate how you should feel.

Partners may grieve and respond differently. That does not automatically mean they care less. Counselling can help if communication becomes difficult. Seek professional support if sleep, eating or daily life remains very difficult, or if panic, distressing memories and avoidance seriously limit you. You can seek help whenever you need it, without waiting for a set period.

Myths and facts about miscarriage

A miscarriage cannot happen without bleeding.

A missed miscarriage may initially cause no noticeable symptoms. Confirmed findings are what matter, not the absence of a warning sign.

Less nausea means the pregnancy has ended.

Pregnancy symptoms fluctuate. Individual symptoms cannot confirm or exclude a loss.

My stress or exercise caused the loss.

Ordinary daily strain is not a typical cause. Many early losses involve developmental processes beyond your control.

I cannot have a child after a miscarriage.

One loss does not establish infertility. After repeated losses, targeted assessment may help, but it cannot predict the outcome with certainty.

Conclusion

A miscarriage may be clearly noticeable or remain unnoticed at first. Careful diagnosis, a clear follow-up plan and care that matches the findings and your needs are what help keep you safe. You do not have to interpret individual symptoms yourself or manage the loss alone.
