When to see a doctor
If you experience severe or worsening symptoms, seek immediate medical attention. Always consult with a healthcare professional for proper diagnosis and treatment.
Causes & Risk Factors
Several factors can contribute to Spontaneous Abortion (Miscarriage).
Most miscarriages happen because of chromosomal abnormalities in the developing embryo or fetus.
Most miscarriages happen because of chromosomal abnormalities in the developing embryo or fetus. During conception, the egg and sperm each contribute 23 chromosomes to create the full set of 46. Sometimes errors occur during this process, resulting in too many or too few chromosomes. When this happens, the pregnancy cannot develop normally, and the body naturally ends it. These chromosomal problems are usually random events, not inherited conditions.
Hormonal imbalances can also cause miscarriage.
Hormonal imbalances can also cause miscarriage. The body needs specific hormone levels to maintain pregnancy, particularly progesterone. If hormone production is inadequate, the uterine lining may not support the developing pregnancy. Thyroid disorders, diabetes, and polycystic ovary syndrome can all affect hormone levels and increase miscarriage risk.
Structural problems with the uterus or cervix account for some pregnancy losses.
Structural problems with the uterus or cervix account for some pregnancy losses. A weakened cervix might open too early, or uterine abnormalities could prevent proper implantation. Severe infections, autoimmune disorders, and certain chronic medical conditions can also lead to miscarriage, though these causes are less common than chromosomal abnormalities.
Risk Factors
- Maternal age over 35 years
- Previous history of miscarriage
- Chromosomal abnormalities in either parent
- Uncontrolled diabetes or thyroid disease
- Severe infections during pregnancy
- Uterine or cervical abnormalities
- Excessive alcohol consumption
- Heavy smoking during pregnancy
- Use of cocaine or other illegal drugs
- Exposure to environmental toxins
Diagnosis
How healthcare professionals diagnose Spontaneous Abortion (Miscarriage):
- 1
When you experience bleeding or cramping during pregnancy, contact your healthcare provider immediately.
When you experience bleeding or cramping during pregnancy, contact your healthcare provider immediately. They'll want to see you quickly to determine what's happening. The initial evaluation typically includes a physical exam to check your cervix and assess how much bleeding is occurring. Your doctor will also ask about your symptoms, when they started, and their severity.

Blood tests play a crucial role in diagnosis.
Blood tests play a crucial role in diagnosis. Your provider will check your hCG (human chorionic gonadotropin) levels - the hormone that pregnancy tests detect. In healthy pregnancies, hCG levels double every 48 to 72 hours during early pregnancy. Declining or slowly rising levels may indicate miscarriage. A complete blood count checks for anemia from blood loss, while blood typing determines if you need special treatment if you're Rh-negative.

Ultrasound provides the most definitive diagnosis.
Ultrasound provides the most definitive diagnosis. A transvaginal ultrasound can detect a fetal heartbeat as early as 6 weeks of pregnancy. If no heartbeat is found when one should be present, or if the embryo appears smaller than expected for the gestational age, this suggests miscarriage. Sometimes multiple ultrasounds over several days are needed to confirm the diagnosis, especially in very early pregnancy when dates might be uncertain.
Complications
- Most people recover from miscarriage without long-term physical complications.
- However, incomplete miscarriage can lead to heavy bleeding or infection if pregnancy tissue remains in the uterus.
- Signs of infection include fever, chills, foul-smelling discharge, or severe abdominal pain.
- These symptoms require immediate medical attention and usually respond well to antibiotics and sometimes additional procedures to remove remaining tissue.
- Recurrent miscarriage, defined as three or more consecutive pregnancy losses, affects about 1 percent of couples trying to conceive.
- If this happens, your healthcare provider will recommend testing to look for underlying causes like chromosomal abnormalities, hormone imbalances, anatomical problems, or blood clotting disorders.
- Many of these conditions can be treated, and most people with recurrent miscarriage eventually have successful pregnancies with appropriate care.
Prevention
- Since most miscarriages result from random chromosomal abnormalities, complete prevention isn't possible.
- However, you can optimize your health before and during pregnancy to reduce some risk factors.
- Taking folic acid supplements before conception and during early pregnancy helps prevent certain birth defects and may reduce miscarriage risk.
- Maintaining a healthy weight, eating a balanced diet, and getting regular exercise all support reproductive health.
- Avoiding harmful substances makes a significant difference.
- This means eliminating alcohol, stopping smoking, and avoiding recreational drugs when trying to conceive and during pregnancy.
- Limit caffeine intake to less than 200 mg per day (about one cup of coffee).
- If you take medications for chronic conditions, work with your healthcare provider to ensure they're safe during pregnancy or find suitable alternatives.
- Managing chronic health conditions before conception improves pregnancy outcomes.
- If you have diabetes, thyroid disease, or other medical conditions, work with your doctor to achieve optimal control before trying to conceive.
- Regular prenatal care helps identify and address problems early.
- While you can't prevent all miscarriages, these steps give your pregnancy the best possible start.
Treatment depends on how complete the miscarriage is and your individual circumstances.
Treatment depends on how complete the miscarriage is and your individual circumstances. If the miscarriage is complete - meaning all pregnancy tissue has passed naturally - you may only need monitoring to ensure your hCG levels return to zero and that bleeding stops. Your doctor will schedule follow-up appointments to track your recovery and watch for signs of infection.
When pregnancy tissue remains in the uterus, you have several options.
When pregnancy tissue remains in the uterus, you have several options. Expectant management means waiting for your body to complete the miscarriage naturally, which can take days to weeks. Many people prefer this approach because it feels more natural, though it requires patience and tolerance for ongoing bleeding and cramping. Medical management uses medications like misoprostol to help expel remaining tissue. This option provides more control over timing while avoiding surgery.
Surgical treatment, called dilation and curettage (D&C), removes remaining tissue through a minor procedure.
Surgical treatment, called dilation and curettage (D&C), removes remaining tissue through a minor procedure. This is often recommended if bleeding is heavy, if signs of infection develop, or if expectant management fails. The procedure is typically done as outpatient surgery under sedation. While it provides immediate completion, some people prefer to avoid surgery if possible.
Emotional support is equally important as physical treatment.
Emotional support is equally important as physical treatment. Many healthcare providers offer counseling resources or support groups. Some people find comfort in memorial services or other ways to acknowledge their loss. Recovery varies - while physical healing usually takes a few weeks, emotional healing takes much longer and looks different for everyone.
Living With Spontaneous Abortion (Miscarriage)
The emotional impact of miscarriage often surprises people with its intensity and duration. Grief is completely normal and doesn't follow a predictable timeline. Some days you might feel okay, while others bring overwhelming sadness. Allow yourself to feel whatever emotions arise without judgment. Many people find it helpful to talk about their experience with trusted friends, family members, or support groups with others who've had similar losses.
