ClassX Video Lessons What happens in your body during a miscarriage? – Nassim Assefi and Emily M. Godfrey
Every year, approximately 23 million pregnancies worldwide end in miscarriage. Despite being common, miscarriage is often surrounded by silence and stigma, leaving many feeling isolated and emotionally distressed. Misconceptions about miscarriage can lead individuals to blame themselves, even though most miscarriages are due to factors beyond their control. Pregnancy is a complex process, and only about one in three fertilized eggs result in a live birth.
Most miscarriages occur within the first 12 weeks of pregnancy. During this time, several hormones play crucial roles: progesterone and estrogen from the ovaries, and human chorionic gonadotropin (hCG) from the fertilized egg. In the first half of the menstrual cycle, estrogen levels rise, followed by progesterone, preparing the uterine lining to support a potential pregnancy.
If the egg is not fertilized, hormone levels drop, leading to menstruation. However, if fertilization occurs, the egg’s outer layer produces hCG, which maintains progesterone and estrogen levels, preventing menstruation and supporting the fertilized egg’s attachment to the uterine lining.
During implantation, complications can arise. Many fertilized eggs fail to attach properly, often passing unnoticed during a menstrual period. Even after successful implantation, chromosomal abnormalities can disrupt embryo development, leading to miscarriage. Contrary to common beliefs, stress, exercise, vaccinations, or past birth control use are not typical causes of miscarriage. Most are due to genetic issues or other uncontrollable health factors.
Miscarriage symptoms vary; some may experience minimal physical signs, while others notice a drop in hCG and progesterone levels, resulting in bleeding and cramping. There are three main treatment options:
This method involves waiting for pregnancy hormones to decline naturally, allowing the body to release the pregnancy tissue. It is effective up to 90% of the time but can involve weeks of unpredictable pain and bleeding.
This option uses two medications: mifepristone and misoprostol. Mifepristone blocks progesterone receptors, while misoprostol induces uterine contractions. This process usually takes 1 to 6 hours and can be managed at home.
In this procedure, a healthcare provider numbs the cervix and uses a thin tube to remove the pregnancy tissue. This method is quick and effective.
Choosing a treatment depends on medical history, personal preferences, and other factors. All three methods are safe and effective, but untreated or incomplete miscarriages can pose serious health risks.
Access to miscarriage treatment can be challenging due to overlaps with abortion care, which may be restricted in some areas. Additionally, over half of the global population lacks access to essential reproductive healthcare. Miscarriage can be a devastating experience, and everyone deserves compassionate care and access to necessary treatments during this difficult time.
Engage in an interactive simulation that models the hormonal changes during early pregnancy. This activity will help you visualize the roles of progesterone, estrogen, and hCG in maintaining a pregnancy. By adjusting hormone levels, you can observe how these changes affect the uterine environment and the likelihood of miscarriage.
Analyze real-life case studies of early pregnancy challenges. Work in groups to discuss potential causes of miscarriage in each scenario, considering factors like chromosomal abnormalities and implantation issues. Present your findings and propose possible treatment options based on the symptoms and medical history provided.
Participate in a workshop aimed at debunking common misconceptions about miscarriage. Research and present on topics such as the impact of stress, exercise, and past birth control use on pregnancy. This activity will enhance your understanding and help you communicate accurate information to others.
Engage in role-playing exercises to explore the challenges of accessing miscarriage care in different regions. Assume roles such as healthcare providers, patients, and policymakers to understand the barriers and discuss solutions for improving access to compassionate care and necessary treatments.
Write a reflective journal entry about the emotional impact of miscarriage. Consider the stigma and isolation often associated with it. Reflect on how increased awareness and support can improve the experiences of those affected. Share your insights in a group discussion to foster empathy and understanding.

Globally, around 23 million pregnancies end in miscarriage each year. Despite its prevalence, miscarriage remains a taboo subject. The experience can feel isolating and, for some, emotionally challenging. Myths surrounding miscarriage contribute to the stigma, leading many to feel responsible for the loss. However, most miscarriages are unpreventable and caused by factors beyond an individual’s control. They occur because pregnancy is a complex process that requires coordination between the fertilized egg and the uterus. In fact, of every three fertilized eggs, only one progresses to a live birth.
Let’s take a closer look at what happens in the body during the first 12 weeks of pregnancy, when a majority of miscarriages occur. Pregnancy is supported by several hormones: progesterone and estrogen, produced in the ovaries, and human chorionic gonadotropin (hCG), released by the fertilized egg. During the first half of each menstrual cycle, estrogen levels rise, followed by an increase in progesterone. These hormones signal the uterine lining to enhance its blood supply and thicken, creating the conditions needed for early pregnancy.
If an egg arrives at the uterus unfertilized, hormone levels naturally drop, triggering contractions and the shedding of the uterine lining during menstruation. However, if the egg is fertilized, its outer layer begins producing hCG. This hormone travels to the ovaries and stimulates the continued release of progesterone and estrogen, preventing menstruation. hCG also binds to receptors on the uterine lining to support the attachment of the fertilized cell mass.
This is a critical stage where complications can arise. For reasons not fully understood, as many as one-third of fertilized eggs fail to properly attach, often passing unnoticed during a normal menstrual period. Implantation is just the first challenge for fertilized eggs that do attach. Once embedded in the uterine lining, the rapidly dividing fertilized egg’s DNA guides its growth. Chromosomal abnormalities can lead to irregular development or halt embryo growth entirely.
Many mistakenly believe their miscarriage was caused by factors like stress, exercise, vaccination, or past birth control use, but the majority are actually due to genetic issues or other health factors beyond a person’s control. Some pregnancy losses may lead to few noticeable physical symptoms, while in other cases, hCG levels drop, followed by a decrease in progesterone, resulting in bleeding and cramping.
There are three treatment options available—two of which are also used in induced abortion procedures. The first option is the “watch-and-wait” method, where a person waits for pregnancy hormones to decline, allowing the pregnancy tissue to be released naturally. This approach works up to 90% of the time but can involve several weeks of unpredictable pain and bleeding.
Others may choose the second option, which involves taking the pills mifepristone and misoprostol in sequence. The first pill blocks progesterone receptors, while the second induces labor, stimulating uterine contractions and causing the cervix to soften and dilate. After taking the second pill, the process typically takes 1 to 6 hours and can often be managed privately at home.
The third treatment option is vacuum aspiration. During this brief procedure, the healthcare provider numbs the cervix and uses a thin tube connected to a syringe-like device to remove the pregnancy tissue. Treatment choice is often based on the individual’s medical history, timeline, expectations, and personal preferences, and all three methods have proven to be safe and effective.
However, without medication or vacuum aspiration, an untreated or incomplete miscarriage can lead to serious health risks. Additionally, because these treatments are the same as those used in induced abortion care, they can be harder to access and may even be criminalized in some areas.
Furthermore, over half of the world’s population lacks access to reliable basic healthcare, including essential reproductive health services. While pregnancy means different things to different people at various points in their lives, losing a pregnancy can be devastating and overwhelming. During this difficult time, everyone deserves care and support, as well as access to life-saving treatments.
