Cryptic Pregnancy – How to Know That You Are Pregnant?

What is Cryptic Pregnancy?

A pregnancy is said to be cryptic when it goes undetected for a long period of time or sometimes till the delivery due to minimal or no symptoms that occur with regular pregnancy. In several cases, the pregnancy goes unnoticed until the would-be mother is 20 weeks into pregnancy and in other cases, the pregnancy may remain undetected till the would-be mother goes into labor, thus making it a completely cryptic pregnancy.

Pregnancy comes with tell-a-tell signs and symptoms – periods stop, the body undergoes several physiological changes, the belly gradually bulges and much more. Though this is the most common form of pregnancy, yet an exception exists. Having an occurrence rate of only 1 in 450 pregnancies, a woman may become pregnant, but without showing any typical signs and symptoms of regular pregnancy. Such a pregnancy is referred to as stealth or cryptic pregnancy and is, in most ways, different from a normal pregnancy.

Why is it Different from Phantom Pregnancy?

Phantom pregnancy is not real pregnancy and is, actually, a physiological disorder wherein the woman exhibits a number of common symptoms and signs of pregnancy without actually being pregnant. Phantom pregnancy is usually referred to as pseudocyesis and is quite different from undetected pregnancy, the major differences being:

  • Periods stop during phantom pregnancy whereas, in case of stealth pregnancy, periods continue though they may reduce and become lighter.
  • Phantom pregnancies do not produce a heartbeat in an ultrasound whereas the use of a Doppler will give indications of a heartbeat in cryptic pregnancies.
  • The abdomen of the woman generally bulges significantly in pseudocyesis, while in case of stealth pregnancy, enlargement of the abdomen isn’t quite pronounced.

What Causes Cryptic Pregnancy?

Though some may believe that the pregnancy goes unnoticed because the woman remains in denial, but that is not the cause of stealth pregnancy in most cases. In fact, the cause of cryptic pregnancy can generally be traced to hormonal imbalance generally caused due to the following reasons –

  • PCOS – Cystic developments in the ovaries can cause hormonal imbalance, thus leading to stealth pregnancy.
  • Low levels of fat in the body can also lead to hormonal imbalance, thus making the pregnancy go undetected.
  • Many women may also develop undetected pregnancy during perimenopause when the body shows various signs of the oncoming phase of menopause.
  • Continued consumption of birth control pills by women can lead to irregular hormone levels in the body, thus increasing the chance of an unexpected pregnancy.
  • Excessive stress also has an influence on the hormonal levels and can be the cause of the undetected pregnancy.
  • Becoming pregnant immediately after a successful pregnancy can prevent the normalization of the hormone levels, thus making the pregnancy cryptic.

Why Does the Pregnancy Remain Undetected?

There are several reasons why a pregnancy may go unnoticed.

  • The woman may continue to have her periods even though she is pregnant. Though the period days usually reduce, it is usually mistaken for a reduced period and not pregnancy.
  • Blood or urine tests may show no indicative signs of the presence of hCG or human chorionic gonadotropin – a hormone released just after the attachment of a fertilized egg to the uterine wall of the woman.
  • Ultrasound tests for pregnancy may give negative results.
  • Not much belly bulging because the baby may be located towards the back of the womb, i.e. towards the spine.
  • The fetal movements are very minimal and the inconvenience caused may be mistaken for a bloated stomach or gas formation.

Key Signs to Know that you are Going Through Cryptic Pregnancy

The symptoms of an undetected pregnancy are quite similar to that of a regular pregnancy. They usually aren’t considered a sign of pregnancy because the most common and determining signs of a pregnancy are minimal or nil. However, if you have one or more of the following symptoms some time or the other and can find no possible cause for the occurrence of these symptoms, you could undergo a test to uncover a cryptic pregnancy if it exists:

  • Vomiting
  • Nausea
  • Fatigue
  • Increased frequency of urination
  • Gradual weight gain
  • Loss of appetite
  • Headaches
  • Heartburn
  • Backache
  • Cramps
  • Usual experience of taste in the mouth

It is to be noted that the severity of these symptoms will vary from woman to another and may not be present at all times. In fact, they tend to be absent most of the times, occurring very suddenly and abruptly, thus leading a woman to believe that these are the symptoms of some other health problem.

Why Cryptic Pregnancy is Different from Regular Pregnancy?

Apart from the fact that you will be missing the common signs of pregnancy like missed periods, belly bulges, positive blood and urine tests, etc., stealth pregnancy has quite a different course as compared to standard pregnancy.

The first difference that occurs is in the development of the fetus into the baby. While standard pregnancies last between 7-10 months, undetected pregnancies last quite long. This happens mainly because of the continued periods during pregnancy which prevents the accumulation of hCG in the mother’s body, thereby delaying the development of the fetus. That is why, undetected pregnancies can last somewhere between 40 weeks to 4 years. However, this doesn’t mean that the baby’s health will be affected. Also, the size of the fetus during the different phases of the pregnancy remains smaller than during standard pregnancy.

Moreover, cryptic pregnancy is accompanied with prolonged labor, the pain and cramps occurring intermittently for a long period of time, usually weeks or sometimes even months. However, like standard pregnancy, the labor pain doesn’t remain at all times. Instead, it comes and goes and does occur even when the labor hasn’t actually started.

Complications that May Arise in Cryptic Pregnancy

Since the pregnancy remains undetected partially or totally, it is usually not possible for the would-be mother to opt for prenatal care. This is not only harmful to the mother but also may affect the baby, especially if the mother leads a very stressed and hectic life.

Moreover, since the prominent signs of pregnancy are mostly missing, complications like blood group incompatibility, diabetes, hypertension, etc. cannot be detected via pre-natal tests and may risk both lives.

Also, since the fetus cannot be generally detected in an ultrasound, doctors may not agree to believe that it is an actual case of pregnancy and thus, delivery of the baby at a hospital may not be possible. In such situation, the woman would have to deliver the baby at home under little or no supervision and proper care which may cause difficulties for both the mother and the newborn.

What Should You Do?

Cryptic pregnancy has a number of problems associated with it. Though undetected pregnancy may not always be a serious situation, it is sure to put your at inconvenience when you deliver a baby suddenly and have no preparation to become a mother at all. So, it would be prudent that you try to prevent stealth pregnancy by trying to find out whether you are pregnant or not.

If you are in the reproductive age group and have sex regularly, followed by the regular use of contraceptives, it is important that you be on the lookout for the chances of an undetected pregnancy. If you keep experiencing symptoms that can happen during pregnancy, go for self-use pregnancy kits. Take tests quite often and be sure to note down the results carefully after each test. If you find that some results are positive while some are negative, it is important that you consult a gynecologist. Tell the doctor about the symptoms and results and see what he/she has to tell you.

Even if the doctor comes with no positive results, do not let your guard down. Try to find out the cause of the symptoms and if their occurrence cannot be related to any other disease or illness, keep taking tests and see other doctors to find out if you are actually undergoing cryptic pregnancy.


Cryptic pregnancy may not be fatal or harmful, but it is best that you avoid it or try to detect it at a very early stage. For that, you need to be very cautious about your health and ensure that you steer clear of the various causes that may eventually lead to an unnoticed pregnancy. Even, if your pregnancy is cryptic, being careful about your health can actually help you uncover the truth so that you can take proper care of yourself and your baby as well. Since cryptic pregnancy usually becomes prolonged and often more painful than standard pregnancy, you need to gear yourself up once you start seeing the various symptoms and obtain some positive results on the home test kits. This will help you be better prepared when you actually deliver the child and ensure that both of you are in good health.

  • I’m so afraid. I think I’m cryptic pg. urine test neg. I see and feel movement. I get bloated abdomen. I’m 55 years old and I’m embarrassed to ask Dr. My last period was 6 months ago and I was with my young bf a few times then all this began. People say it’s menopause. But why is there moving? 3 home urine tests all negative. I’m afraid. Hope it’s not tumors or worms!!!!!!

    • I am possibly cryptically pregnant. I would be 19 weeks along. I am starting to feel movement. Went to dr, said saw nothing on ultrasound. I am very confused.
      I am 50 years old.
      I had 3 children and know what baby movement feels like. Baby movements are internal and not external to be seen.

      Referred me to gastro doc.

      I feel that is not answer.

      Any input appreciated.

  • How are guys able to know their cryptic pregnancy lasted a certain duration yet we are told its hard to be detected.?

  • Hi am Bei, I am 48yrs old and going through the same thing. For the past 2 1/2 months, my periods have gone from 5-7 days to barely 2 days. I have all the symptoms of pregnancy, nausea, large tender breast, food cravings, frequent urination and my labia and vagina are a blueish color. I have gone to the Dr’s and my hcg levels is 2 and negative urine tests. I’m not crazy and I know my body. Trying to find a Dr that will do an ultrasound. Meanwhile, I am taking care of myself and preparing for a little one.

  • Hello I’m non. I am experiencing cryptic pregnancy. I have diabetes and high blood pressure. The HCG levels are negative for urine and blood work. Still my belly gets bigger! I don’t know what to do. I went to the er, health department,and 2doctors. They all say that I am in need of a psychologist and I am too fat . And they say that I have kidney stones/gall bladder stone. I am not hurting. There is no blood in my urine. I pee just fine. I do have a mental health issue. Um… it is embarrassing to have it. I lost my boyfriend. He thinks I am trying to pin him down and threatening him. Still my stomach moves and I have frequent movement in my belly. Sometimes it moves with my music. I keep gaining weight. The harder I excerise my stomach doesn’t flatten. last time I ignore the symptoms I has a miscarriage at home after a lightning strike hit my stomach. Now I am afraid to ask for help. No one is going to help me with this.what if I am crazy? What if I am lying? Maybe I think I am going to to die in child birth or my baby going to turn to stone in my stomach. Why can’t I have a normal HCG detectable pregnancy. Why me?
