6 Main Causes for Cryptic Pregnancy

Though the exact reasons for cryptic pregnancy are not yet known, there are several factors that can be attributed to this condition. Problems like polycystic ovarian syndrome, very early menopause, recent pregnancy, very low body fat, some birth control pills, stress etc can precipitate cryptic pregnancy. Let us see how these factors can increase your chances of cryptic pregnancy. But one thing that is common to all these factors is the risk of hormonal imbalance.

Recent pregnancy

If you had been pregnant recently, your hormones may not have stabilized at their usual level within this time. It needs some time for the hormone levels to get back to their levels prior to pregnancy. This can create an imbalance in the level of various hormones. If you indulge in unprotected sex during this window of time, you may have a cryptic pregnancy since the level of HCG may not be detectable or significant at this time.

Low Body fat 

If you have very low body fat then you are susceptible to hormonal imbalance. Female hormones like estrogen are dependent on body fat. This is because the thighs in women have several estrogen receptors. These receptors bind with estrogen produced in the body of women. The production of estrogen is controlled by the pituitary gland, but it is produced in the placenta, the organ that appears during pregnancy and disappears after child birth. When body fat becomes too low the gland reduces the production of estrogen. Estrogen has a strong bearing on the symptoms of pregnancy like growth of breasts, morning sickness, weight gain etc. Not only that, it also regulates the production of other hormones like HCG. So very low body fat may result in suppression of estrogen which may then lead to suppression of symptoms as well as suppression of production of HCG, the marker of pregnancy.

Birth control pills

Some birth control pills may release hormones which have the effect of suppressing the normal hormones in women. Some birth control pills are high in progesterone. But if you have already conceived a child, but still continue to take contraceptives, the pill will rather help your pregnancy while you are still unaware of pregnancy.

Very early menopause

If you have just started to show the signs of menopause then it is very likely that pregnancy symptoms will not show up. Menopause can start as early as in the 30s of a woman and in such cases pregnancy often goes unnoticed.


High stress level may well contribute to cryptic pregnancy. If you are under tremendous stress, your body will have high levels of stress hormones. This has the capacity to create a hormonal imbalance. If you are pregnant during this time the symptoms of pregnancy may not become obvious. You may not be aware of your pregnancy. Conclusion It is difficult for a woman to become aware of pregnancy if she is suffering from cryptic pregnancy. You may not have symptoms like morning sickness, high weight gain etc. Moreover, you may also have mild and irregular menstruation. You may also have vaginal bleeding with spotting. The symptoms can be so mischievous sometimes that you may not at all be aware of your pregnancy until you get labor pain. However, in most cases women become aware within 20 weeks or so.
