The Gilmour Foundation, an Internet-based foundation which styles itself as an expert on cryptic pregnancy, claims a cryptic pregnancy is one that is missed by pregnancy tests and ultrasounds. They claim these pregnancies occur because of an abnormally slow-growing fetus, and gestate for years or even decades. The foundation has said that this causes the [[human chorionic gonadotropin]] (hCG) [[hormone]] to be too low to be detected by medical tests and, because the pregnancy is smaller or located outside the uterus, it is missed on [[ultrasound]]s.<ref>{{Cite web|url=https://www.crypticpregnancysupportgroup.com/what-is-a-cryptic-pregnancy-and-what-causes-it.html|title=What is a Cryptic Pregnancy and What Causes it?|website=Cryptic Pregnancy Support Group & The Gilmour Foundation|access-date=2017-12-30}}</ref> However, there is no medical literature to support the existence of cryptic pregnancy as described by the Gilmour Foundation.

For the most part, this form of cryptic pregnancy is a psychological issue. Some people with this mental illness show [[symptoms of pregnancy]], such as [[amenorrhea]], weight gain, nausea, etc., which could be caused by the delusion or by its underlying cause. |

[[Mary I of England|Queen Mary I]] of [[England]] is rumored to have experienced false pregnancy, which may be considered cryptic, because she continued to believe she was pregnant past the expected due month. However, because of the limitations of medical technology, and the delicacy of inspecting the body of the queen, doctors would have had great difficulty in verifying a pregnancy, including whether it was a [[neoplasm|tumor]] or a [[molar pregnancy]]. During one of her false pregnancies, Mary believed herself to be pregnant for nearly a year after her period stopped, when suddenly her abdomen flattened without her going into labor.{{Citation needed|date=November 2019}} |

The term cryptic pregnancy is used by medical professionals to describe a pregnancy that is not recognized by the woman who is pregnant until she is in labor or has given birth.[1] The term is also used online for a special form of false pregnancy (pseudocyesis), or delusion of pregnancy, in which a woman who has no medical verification of pregnancy believes that she is pregnant.
Medically cryptic pregnancies
[edit]The television series I Didn't Know I Was Pregnant[2] shared the stories of women who had experienced medically cryptic pregnancies. They did not realize they were pregnant until they were in labor or had given birth. Nearly all the featured stories involved women who had intermittent bleeding throughout pregnancy that they misinterpreted as menstruation, while some cited not having regular periods due to polycystic ovarian syndrome (PCOS), or other conditions that are associated with infertility. The women involved often did not gain weight or experience other major symptoms of pregnancy, such as morning sickness or breast sensitivity. Those who did experience some symptoms of pregnancy either claimed to attribute the symptoms to an existing condition, claimed to have taken a home pregnancy test and gotten a negative result, or both.
A few of the stories involved women who had known they were pregnant and experienced an early miscarriage, only to realize they were still pregnant when the baby was being born. It is common that after the birth the new mother looks back and realizes that there were some signs of pregnancy she had ignored. For women who have had a typical pregnancy, the assumption is that there is no way to not "feel" a pregnancy. However, obstetricians on the show explained that, depending on the position of the placenta, the sensations of a baby moving can be minimal. In 2015, the show's spin off, I Still Didn't Know I Was Pregnant, featured women who had experienced multiple medically cryptic pregnancies.[3]
Causes
[edit]The causes of medically cryptic pregnancies are either physiological, that is, there were no recognizable symptoms of pregnancy, or can be due to psychological problems. For example, denied pregnancy is a condition in which a woman is mentally unable to accept that she is pregnant and so may go part way or all the way through a pregnancy unconscious of her pregnancy. This phenomenon is sometimes linked to other mental health diagnostic labels.[4] However, denied pregnancy makes up only a proportion of all unknown pregnancies.
Epidemiology
[edit]According to a 2023 study, 1 in 475 pregnancies can classify as a cryptic pregnancy where pregnancy is not discovered until at least 20 weeks.[5]
One in 7,225 pregnancies are unknown at the time the mother gives birth.[6]
