Understanding Miscarriage

Course / Understanding Miscarriage

Nobody Wants to Be Here

To acknowledge the emotional difficulty of miscarriage while framing it within the context of a fertility journey, and to introduce the role of a structured, supportive agency.

Key Content Points:

  • Acknowledging the Reality: Begin by validating that experiencing a pregnancy loss during a surrogacy journey is profoundly disappointing for all parties involved—the intended parents and the surrogate. It’s a path no one anticipates.
  • Reframing the Context:
    • Clinical Commonality: Emphasize that miscarriage is, unfortunately, a common outcome in human reproduction, with approximately 1 in 4 clinically recognized pregnancies ending in loss.
    • Not a Reflection of the Surrogate: Clearly state that in the vast majority of cases, miscarriage is not caused by anything the surrogate did or did not do. It is typically related to factors intrinsic to the embryo itself.
    • A Step in the Process: Frame the miscarriage not as a definitive failure, but as a specific outcome of one embryo transfer. It provides critical information that can guide the next steps.
  • The Surrogacy4All Framework of Support:
    • Explain the agency’s role in providing immediate, coordinated support—clinical, logistical, and emotional.
    • Highlight the importance of a unified team: the intended parents, the surrogate, the clinical team at the fertility clinic, and the agency case manager.
    • Reassure that the medical and logistical aspects are handled professionally, allowing all parties to focus on processing the event.

Defining Miscarriage

To provide clear, clinical definitions of different types of miscarriage, removing ambiguity and empowering intended parents and surrogates with knowledge.

Key Content Points:

  • Clinical Definition: A miscarriage (or “spontaneous abortion” in medical terms) is the spontaneous loss of a pregnancy before the 20th week.
  • Breakdown of Common Types:
    • Chemical Pregnancy: A very early miscarriage that occurs just after implantation, detected only by a positive HCG test that does not rise appropriately. It often happens before anything can be seen on an ultrasound.
    • Threatened Miscarriage: When there is vaginal bleeding, but the cervix remains closed and ultrasound shows a continuing pregnancy. The pregnancy may or may not progress.
    • Missed Miscarriage (Silent Miscarriage): The embryo has ceased developing or never developed, but the body has not yet recognized the loss or begun to expel the pregnancy tissue. There may be no symptoms like bleeding or cramping. Diagnosis is typically made via ultrasound.
    • Inevitable or Incomplete Miscarriage: The cervix has begun to dilate, bleeding and cramping are present, and the body is in the process of passing the pregnancy tissue. An ultrasound will show that some tissue remains in the uterus.
    • Complete Miscarriage: The body has naturally passed all pregnancy tissue. The uterus is empty on ultrasound, and bleeding and cramping typically subside.

Is This a Miscarriage

To outline the potential signs of a miscarriage and stress the critical importance of medical evaluation for any concerning symptoms.

Key Content Points:

  • Potential Signs and Symptoms to Report:
    • Vaginal Bleeding: Ranging from light spotting to heavy bleeding, potentially with clots.
    • Abdominal Pain or Cramping: Can range from mild to severe.
    • Sudden Cessation of Pregnancy Symptoms: (e.g., breast tenderness, nausea).
    • Fluid or Tissue Passing from the Vagina.
  • Crucial Disclaimer: Emphasize that these symptoms do not always mean a miscarriage is occurring. For example, light spotting and cramping can be normal in early pregnancy. However, any concerning symptoms warrant immediate communication with the fertility clinic or obstetrician.
  • The Diagnostic Imperative: Stress that a diagnosis of miscarriage should never be based on symptoms alone. It must be confirmed through two key diagnostic tools: Quantitative HCG (Beta) Blood Tests and Transvaginal Ultrasound.

Beta & HCG Numbers Explained

To demystify Beta HCG testing, explaining what the numbers mean and how they are interpreted in early pregnancy.

Key Content Points:

  • What is HCG? Human Chorionic Gonadotropin is a hormone produced by the placenta shortly after implantation.
  • The Importance of Trend Over a Single Number: A single HCG value has limited use. The pattern of rise over 48-72 hours is the critical diagnostic factor.
  • Interpreting the Trends:
    • Viable Pregnancy: In early pregnancy, HCG levels typically double approximately every 48-72 hours. (Note: The doubling time slows as the pregnancy progresses).
    • Concerning Patterns:
      • Slow-Rising HCG: A rise that is less than the expected doubling rate can indicate a failing pregnancy (e.g., ectopic pregnancy or impending miscarriage).
      • Falling HCG: Declining levels indicate that the pregnancy is no longer viable.
      • Plateauing HCG: A lack of significant rise is also a strong indicator of a non-viable pregnancy.

When Ultrasound Takes Over: Explain that once HCG levels reach a certain threshold (often between 1,000-2,000 mIU/mL), a gestational sac should be visible on a transvaginal ultrasound. At this point, ultrasound becomes a more reliable diagnostic tool than HCG levels alone.

Ultrasound to Diagnose Miscarriage

To explain how ultrasound is the definitive tool for diagnosing miscarriage and what specific findings clinicians look for.

Key Content Points:

  • The Gold Standard: Transvaginal ultrasound is the primary method for confirming viability in early pregnancy.
  • Key Developmental Milestones and Timelines:
    • Gestational Sac: Visible around 4.5-5 weeks gestation.
    • Yolk Sac: Appears inside the gestational sac around 5.5 weeks. Its presence confirms that the structure is a true gestational sac and not a “pseudosac.”
    • Fetal Pole: The early embryo, visible around 6 weeks.
    • Cardiac Activity: A fetal heartbeat should be detectable once the fetal pole reaches a certain size (typically around 5-7mm, at approximately 6-6.5 weeks gestation).
  • Ultrasound Criteria for Diagnosing Miscarriage:
    • Clear Diagnosis:
      • An empty gestational sac measuring a certain mean diameter (e.g., 25mm) with no yolk sac or fetal pole.
      • The presence of a fetal pole measuring a certain length (e.g., 7mm) with no detectable cardiac activity.
    • Highly Suspect Findings (Requiring follow-up scan):
      • A gestational sac without a yolk sac when the mean sac diameter is 13-25mm.
      • The absence of a fetal heartbeat when the fetal pole is less than 7mm.
      • The absence of a live embryo on a follow-up scan 7-14 days after an initial scan that showed a gestational sac without a yolk sac or fetal pole.

Reiterate that a diagnosis is made by correlating the ultrasound findings with the patient’s history and HCG levels, and that the clinical team will guide the next steps for management based on this comprehensive picture.
