A miscarriage (spontaneous abortion), defined as the loss of a fetus before the 20th week of pregnancy, is one of the most common complications during early pregnancy. A study involving over 50,000 women shows that about 43% of all women who have already given birth have experienced at least one miscarriage beforehand (Cohain et al., 2017). This number may even be higher in reality, as many women experience a miscarriage before they even know they are pregnant. The loss of a child can pose a profound emotional and physical challenge, often leading to questions, fears, and grief for the affected women. A common question that arises is how and when can I become pregnant after a miscarriage.
Causes of a Miscarriage
A miscarriage can be caused by a variety of factors; here are the most common causes:
Chromosomal Abnormalities
The most common cause of miscarriages is chromosomal abnormalities in the embryo. These abnormalities often occur randomly during fertilization or cell division and result in the embryo not being able to develop normally. Chromosomal abnormalities, such as those seen in Down syndrome (Trisomy 21), increase with age, particularly from the age of 35.
Hormonal Imbalances
Imbalances in hormone levels, especially luteal phase defects, thyroid dysfunction, and polycystic ovary syndrome (PCOS), can lead to miscarriages.
Anatomical Anomalies
Structural abnormalities or adhesions in the uterus can increase the risk of miscarriage. These can usually be identified by ultrasound.
Infections
Certain infections, such as toxoplasmosis, can lead to miscarriages by damaging the placenta or the fetus.
Immunological Causes
The immune system can reject tissue properties inherited from the father, thereby preventing a successful pregnancy.
Thrombophilia (Blood Clotting Disorder)
The Factor V Leiden mutation can lead to vascular blockages. Microthrombi can prevent an embryo from successfully implanting.
Chronic Maternal Conditions
Conditions such as diabetes, high blood pressure, or autoimmune diseases in the mother can increase the risk of miscarriages.
Lifestyle Factors
Smoking, excessive alcohol consumption, drug abuse, and certain environmental factors such as radiation, chemicals, and pesticides can also increase the risk of miscarriage.
Idiopathic Infertility
Sometimes, no identifiable reasons can be found for a miscarriage.
Becoming Pregnant After a Miscarriage
The loss of a child can bring deep sadness and uncertainty, but it is important to know that another pregnancy is possible. Many women successfully become pregnant after a miscarriage. Certain medical examinations can help ensure that nothing stands in the way of a new pregnancy.
Follow-up Examination
An appointment with your gynecologist is important to identify possible complications for a subsequent pregnancy.
Curettage
In certain cases, it may be necessary to remove pregnancy tissue from the uterus (curettage). A curettage may be required because remaining tissue can lead to complications such as infections or excessive bleeding. It may also occur that the fetus has died but has not been expelled.
During a curettage, a doctor uses a special instrument to gently remove the pregnancy tissue from the uterus. The procedure usually takes only a few minutes and is performed under local anesthesia. During and after the procedure, light to moderate pain and cramping may occur.
Blood Tests / Hormonal Status
A blood test plays a crucial role in diagnosing the cause.
It can provide insight into the following aspects:
Hormonal Status
HCG (Human Chorionic Gonadotropin): HCG is the pregnancy hormone produced during pregnancy. An increase in HCG levels in the first few weeks is crucial, while a decline may indicate a miscarriage. Monitoring HCG levels helps doctors assess whether the miscarriage is complete and if any pregnancy tissue may still be left in the uterus.
Progesterone: Progesterone is necessary to maintain the pregnancy. A low progesterone level may indicate that the pregnancy was not adequately supported by the body.
Rh Incompatibility
If an Rh-negative woman carries an Rh-positive child, her immune system may produce antibodies against the Rh-positive red blood cells of the fetus if the fetus’s blood comes into contact with the mother's blood. This can particularly occur during a miscarriage.
These antibodies can be dangerous in future pregnancies. If the mother has produced antibodies, these can attack the fetus's blood, leading to severe health problems for the child.
Detection of Infections and Autoimmune Diseases
Possible infections and autoimmune diseases in the mother can be causes of a miscarriage.
Nutrient Deficiency
A deficiency in important nutrients such as iron or folic acid can affect fertility and the ability to maintain a pregnancy.
Genetic Diagnostics
Blood tests of the parents for genetic anomalies can provide insights, especially if multiple miscarriages have occurred.
Consequently, embryos in an IVF treatment can be tested for genetic anomalies through preimplantation diagnostics (PID) before being transferred to the uterus.
Recommended Waiting Time Before Trying to Conceive Again
After a miscarriage, many women face the question of when the right time is for another pregnancy. Specialists recommend waiting at least one full menstrual cycle or up to three months before attempting to conceive again. The World Health Organization even recommends a waiting time of around six months.
However, there is no data to support these recommendations. On the contrary, a 2016 study showed that a shorter waiting time of 0-3 months could achieve higher live birth rates (Schliep et al., 2016).
Waiting for a regular menstrual cycle can help determine the timing of ovulation and thus better identify fertile days.
Healthy Lifestyle for Physical and Emotional Strength
A miscarriage is an emotional and physical turning point in a woman's life. In addition to medical follow-up, it is essential to consider lifestyle changes and the proper intake of micronutrients. These aspects can support physical health and increase the chances of a successful future pregnancy.
Healthy Diet
A balanced diet is crucial for promoting fertility. The following foods can support female fertility:
- Fruits and Vegetables: These are rich in antioxidants, vitamins, and minerals.
- Whole Grains: Whole grains such as oatmeal, whole grain bread, and brown rice are high in fiber and support digestion and blood sugar levels.
- Protein Sources: Lean meat, fish, legumes, nuts, and seeds provide essential amino acids and are important for cell repair and regeneration.
- Fats: Healthy fats from avocados, nuts, seeds, and olive oil are essential for hormone production and overall health.
Micronutrients
The intake of certain micronutrients can improve egg quality and support the body during the healing process after a miscarriage. Here are the key micronutrients for egg quality:
- Folic Acid (Folate): Folic acid is crucial for cell division and should be taken even before pregnancy. However, around 50% of women may not absorb folic acid, so the intake of the bioavailable form, folate, is recommended. Scientific studies have confirmed that folate intake is associated with a reduced risk of miscarriages (Gaskins et al., 2014).
- N-Acetyl-cysteine: A study showed that women who took N-acetylcysteine (NAC) and folic acid had a 2.9 times higher likelihood of continuing their pregnancy beyond the 20th week (Amin et al., 2008).
- Vitamin D: Vitamin D plays a significant role in female fertility. According to a 2022 study, women with a diagnosed vitamin D deficiency (<50 nmol/L) have an increased risk of miscarriage compared to women with sufficient vitamin D levels (Tamblyn et al., 2022).
Physical Activity
Regular physical activity not only supports physical health but also mental health. Moderate activities such as walking, cycling, and yoga are recommended for stress management, along with strength training to build muscle and improve overall fitness.
Psychological Support
Emotional health is just as important as physical health. Professional psychological counseling, support groups, and sharing with close friends and family can help cope with grief and manage anxiety.
Stress Management
Stress can negatively impact fertility. The following techniques can help reduce stress:
- Meditation and Mindfulness: These practices promote inner calm and help stabilize emotional health.
- Hobbies and Social Contacts: Taking time for activities that bring joy, distract from the desire for children, and surround oneself with supportive people.
Conclusion: Becoming Pregnant After a Miscarriage is Possible
Experiencing a miscarriage can be physically and emotionally burdensome for affected women. Despite the grief, there is hope, as becoming pregnant after a miscarriage is possible. Important steps include medical examinations to determine the causes and establish necessary treatments. Additionally, a balanced diet, micronutrient intake, regular exercise, and stress management can be crucial for supporting fertility and emotional well-being. It is important to take time to heal, as with the right preparation and support, it is possible to find new hope and realize the desire for children.
