A cryptic pregnancy or denied pregnancy is a lack of subjective awareness of pregnancy until the end of gestation in pregnant women. This condition has an incidence of 1:475. Causes are not clear; it is thought to be either psychological or caused by low concentrations of the pregnancy hormone hCG.
A small group of women believe cryptic pregnancy is a pregnancy where urine and bloodtests are negative because of low hCG and that even ultrasounds don't show the fetus because it grows much more slowly. There is no medical literature to support their case.
