Cryptic pregnancy is a fascinating phenomenon that has puzzled both medical professionals and expecting mothers alike. In this blog post, we will delve into hidden pregnancy, exploring its definition, signs and symptoms, causes, emotional impact, and more. Whether you’re an expecting mother or simply curious about pregnancy-related topics, join us on this enlightening journey.

It’s estimated that approximately 1 in 475 women will experience a cryptic pregnancy until 20 weeks of gestation. Hidden pregnancy is a condition where a woman remains unaware of her pregnancy until very late in the gestation period or even until delivery. While it sounds like something out of a movie, cryptic pregnancy is a real and relatively rare phenomenon. Despite its rarity, the impact on those who go through it can be significant.

What is Cryptic Pregnancy?

Cryptic pregnancy, also known as stealth pregnancy or denial of pregnancy, refers to a pregnancy that goes undetected by the woman herself and often by healthcare professionals as well. The reasons behind this lack of awareness vary, but it’s important to understand that it’s not a conscious decision to deny or ignore the pregnancy. It is characterised by irregular or absent menstrual periods, minimal or no pregnancy symptoms, and negative pregnancy tests.

Signs and Symptoms of Cryptic Pregnancy

One of the most intriguing aspects of cryptic pregnancy is the absence of typical pregnancy symptoms. While some women may experience certain symptoms such as weight gain, abdominal distension, or intermittent bleeding, many others will have no noticeable signs of pregnancy. The lack of these symptoms, combined with irregular menstrual cycles, can contribute to the confusion and disbelief surrounding this type of pregnancy.

Indicators to look out for

  • Missed period: While most individuals recognise pregnancy due to a missed period, this is not always the case. If your periods are irregular, you may not notice a missed period as a sign of pregnancy. However, people may experience spotting or light bleeding, which can be mistaken for a period.
  • Fetal movement: Most individuals do not feel the fetus move until about halfway through pregnancy, so around the middle of the second trimester. If you have an anterior placenta (located at the front of your belly), it may be more challenging to perceive kicks. In the case of cryptic pregnancy, this could be why you are unaware of being pregnant.
  • False negative pregnancy test result: This occurs when someone is actually pregnant, but the test indicates otherwise. If you do not use an at-home pregnancy test correctly, you may receive an inaccurate result. To be certain, it is always best to consult a healthcare provider to confirm pregnancy. Another way you can check whether you’re pregnant or not is by doing one of the pregnancy blood tests.
  • Weight gain or swollen belly: Some individuals may not realise they have gained weight due to pregnancy, or they may attribute an unusually bloated belly to a particular food.

Please note that this response does not constitute medical advice. If you have concerns or questions about pregnancy, consult a qualified healthcare professional.

Factors Contributing to Cryptic Pregnancy

Various factors, both physiological and psychological, can influence cryptic pregnancy. Hormonal imbalances or irregularities can disrupt the usual hormonal markers of pregnancy and lead to false-negative pregnancy tests. Certain medical conditions, such as polycystic ovary syndrome (PCOS) or uterine abnormalities, can also affect the accuracy of pregnancy tests. Additionally, psychological factors, such as subconscious denial or a lack of awareness about pregnancy symptoms, can contribute to a woman’s unknowingness. 

Potential complications of a cryptic pregnancy?

Complications arising from a cryptic pregnancy stem from the lack of awareness about one’s condition. These complications may include:

  • Absence of prenatal care: Unaware of the pregnancy, individuals do not receive the necessary prenatal care, such as vital bloodwork, nutritional guidance, ultrasounds, and other essential support required for a healthy pregnancy. Furthermore, not knowing about the pregnancy could result in unassisted labour without the aid of skilled healthcare professionals.
  • Necessity for lifestyle adjustments: Smoking and consuming alcohol have detrimental effects on pregnancy. In the case of a cryptic pregnancy, individuals may unknowingly engage in these harmful practices or use medications and supplements that are generally unsafe for expectant mothers.
  • Elevated risk of medical conditions: Without proper care or diagnostic tests, conditions like gestational diabetes or preeclampsia may go undetected.
  • Heightened risk of congenital conditions: The fetus is at a higher risk of developing congenital conditions due to the lack of genetic tests, like NIPT, or other evaluations that aid in diagnosing the health of the baby.

It is crucial to highlight the potential risks associated with a hidden pregnancy to promote awareness and encourage individuals to seek appropriate medical support. This fact has been highlighted in studies saying that infants born from cryptic pregnancies are more likely to be born prematurely, placing them at risk of poor growth and respiratory issues.

Emotional Journey of Cryptic Pregnancy

The emotional journey of hidden pregnancy is complex and can vary greatly from woman to woman. Discovering that you are pregnant after an extended period of unknowingness can evoke a range of emotions, including shock, confusion, and even joy. It’s crucial for women experiencing cryptic pregnancy to seek emotional support from their partners, family, and healthcare professionals. Counselling and therapy can also be beneficial in navigating the emotional challenges that may arise.

Cryptic Pregnancy FAQs


  • Can stealth pregnancy be prevented?

    Cryptic pregnancy, also known as hidden pregnancy, cannot be prevented as it is often caused by physiological or psychological factors that are beyond an individual’s control.

  • Can cryptic pregnancy occur in women who have regular periods?

    Yes, cryptic pregnancy can occur in women with irregular or regular menstrual cycles. Irregular periods do not necessarily indicate cryptic pregnancy, and regular periods do not guarantee the absence of pregnancy.

    It’s important to consult with a healthcare professional, such as a gynaecologist, for accurate information and personalised insights into cryptic pregnancy.

A Comprehensive Guide to AMH Blood Test: Its Significance and Connection to IVF

Ever wondered how a simple blood test could offer a glimpse into your fertility? In this blog post, we’ll delve into one of the most crucial hormones affecting fertility—the Anti-Mullerian Hormone (AMH). If you’ve heard of this hormone and wondered what role it plays in fertility or IVF treatments, you’re in the right place.

What is the AMH Blood Test?

An AMH (Anti-Mullerian Hormone) blood test measures the levels of AMH in a woman’s blood. Produced by the cells of the ovarian follicles, AMH serves as a reliable marker of ovarian reserve, effectively indicating a woman’s fertility potential. This test aids clinicians and fertility specialists in predicting a woman’s response to fertility treatments, particularly in vitro fertilisation (IVF).

What is the Anti-Mullerian Hormone (AMH)?

The Anti-Mullerian Hormone, first discovered by Alfred Jost in the 1940s, plays a crucial role in the sexual development of foetuses. AMH was initially known for its role in male sexual development, but subsequent research has unearthed its pivotal part in female fertility. In women, the hormone is released by the antral follicles, the small sacs in the ovaries that hold the eggs.

Why is the AMH Blood Test Important?

As AMH levels correspond to the number of remaining eggs in the ovaries, the AMH blood test offers a reliable gauge of a woman’s ovarian reserve. However, it’s essential to understand that AMH levels do not directly correlate with the quality of eggs.

Low AMH levels might indicate a diminished ovarian reserve, which could be a concern for women attempting to conceive naturally or through IVF. In contrast, higher AMH levels may suggest conditions like Polycystic Ovary Syndrome (PCOS).

When is an AMH Blood Test Required?

The AMH test may be recommended in several circumstances:

  1. Evaluating Ovarian Reserve: AMH levels help assess the number of eggs remaining in the ovaries. The test may be suggested for women approaching their mid-30s, those with a family history of early menopause, or those who’ve previously undergone chemotherapy or pelvic surgery.
  2. Diagnosing PCOS: Elevated AMH levels may be indicative of PCOS, a common condition affecting a woman’s ovaries and ovulation.
  3. Determining IVF Success: Before starting IVF treatment, clinicians may order an AMH test to better predict how the ovaries will respond to the fertility drugs used to stimulate egg production.

Connection between AMH Levels and IVF

The AMH blood test holds significant value in the field of assisted reproductive technology, especially IVF. It helps clinicians devise personalised treatment strategies for their patients.

For women with low AMH levels, special considerations may be needed during the stimulation phase of IVF. These women often respond less to ovarian stimulation, leading to a smaller number of eggs retrieved, which can affect the success rate of IVF. Conversely, women with high AMH levels might be at risk for Ovarian Hyperstimulation Syndrome (OHSS), a condition that can occur when the ovaries are overly stimulated by fertility drugs.

When is the Best Time to Have an AMH Blood Test?

An AMH blood test can be performed at any time during a woman’s menstrual cycle, as AMH levels remain relatively constant throughout. However, many fertility clinics might suggest the test as a part of an initial fertility assessment or prior to beginning fertility treatments like IVF.

In Conclusion

The AMH blood test serves as a potent tool in assessing a woman’s ovarian reserve and planning personalised fertility treatments. Whether you’re attempting to conceive naturally, preparing for IVF, or just wish to know more about your fertility, an AMH test could offer invaluable insights. Always consult with a fertility specialist to discuss your options and understand what’s best for your individual circumstances.
