What is a cryptic pregnancy? What causes a stealth pregnancy? And what are the symptoms? Find out everything here

We’ve all heard the story: a woman goes into hospital with stomach pains and comes out with a baby. And, if you’re anything like us, you’ll have wondered aloud "how didn’t she realise that she was pregnant?".

But it’s not because they’re in denial, or because they don’t know how sex works.

In fact, their experiences are a product of what is known as a “cryptic pregnancy” - when a woman doesn’t find out that she’s pregnant until 20 weeks along or later - which affects 1 in 450 women.

What is a cryptic pregnancy?

It is a pregnancy where there is little or no detectable hCG (human chorionic gonadotropin) in the mother’s system.

This is the hormone that makes a home pregnancy test turn positive. A baby that produces a scant amount amount of HCG might go "under the radar," failing the pregnancy test and going undetected by the mother.

Sweet pregnancy cravings

Cravings for sugary foods are probably the most obvious – what with morning sickness, low moods and health problems, you're likely to be feeling a bit run down! Subseqeuntly, you'll be craving foods that'll give you a quick boost: simple carbohydrates like sweets, chocolate or white bread.Protein-rich foods (like eggs, dairy and meat) can help banish sweet cravings; they keep you fuller for longer, which can be great if you're battling long periods of nausea and can't stomach a lot of food. If you really need a sugar fix, though, go for fruit first – frozen berries can be great if you're craving ice cream, and exotic fruit like dried mango can be a good substitute for jelly sweets. If all you can think about is chocolate, go for the dark variety – it contains antioxidants that can boost the immune system, and there's less sugar.

Salty pregnancy cravings

Cravings for salt are quite obvious – usually, your body is crying out for some sodium. It can be a sign of stress – if you're stressed out, your body will be producing more adrenaline, and the adrenal glands need minerals to function properly. Salt cravings can also be an indication of low blood pressure, which can be common in the early stages of pregnancy.Plain rice with a tiny bit of soy sauce is a good option, as it's a complex carbohydrate that'll keep you fuller for longer. If you do go for crisps, try the lighter varieties that are lower in saturated fat and salt. As a rule, though, if you can see the grains of salt, there's too much on there!

Spicy pregnancy cravings

Spicy food causes the body to release small amounts of endorphins (the same feel-good hormones you release when exercising), so maybe your hormones are making you feel a bit down.Spicy food isn't really bad for you – a vegetable curry, some chicken tikka or maybe a Mexican wrap with hot salsa aren't exactly weight-gain inducing. Just don't overdo it; your digestive system might not forgive you!

Sour pregnancy cravings

Sour cravings could be linked to your digestive health, as they cause your mouth to produce a lot of saliva, which kick-starts digestion.Lemons ranked third in a recent study of unusual cravings, so something with a sharp citrus flavour could be just the ticket. Before you reach for the Haribo SourMix, though, try lemon sorbet, which is made with fruit juice and has less than 100 calories per serving. Alternatively, a citrus-based fruit salad or a glass of fruit squash could work wonders for your cravings.

Non-specific pregnancy cravings

Sometimes, you just get the urge to eat anything and everything around you. This could be due to feeling down (thanks to yet more hormonal changes) or just feeling bored. Whatever your reasons, we can't vouch enough for knowing the difference between genuine hunger and emotional hunger.If you really need to consume something, try a hot or cold drink first. The temperature might distract your brain for a while, and ice has been a popular craving antidote among pregnant ladies for years – to the extent that, nowadays, ice lollies are the number 1 odd craving among mums-to-be!If there's literally nothing else that'll satisfy your craving, just go for it. Pregnancy is one time not to skimp on calories. In fact, you need an extra 300 calories a day to ensure a healthy baby.The only way you could be harmed by a craving is if you're only eating the food you crave – and therefore depriving your body of other nutrients.

What causes a cryptic pregnancy?

It appears that cryptic pregnancies occur when women suffer from a hormonal imbalance.

This can be due to:

  • Poly Cystic Ovarian Syndrome (PCOS)

  • Hormones haven't gone back to normal after a recent pregnancy and/or breastfeeding

  • Undetected peri-menopause

  • Low body fat

  • Using a birth control method such as Norplant, Nexplanon, Depo-provera or the mIRENA cOIL

  • Using hCG oral drops or injections for weight loss

  • Taking the morning after pill

  • Eating large amounts of soy products

According to some doctors, a cryptic pregnancy can also be caused when the woman is simply stressed out. Apparently, in this case, it's in the foetus's best interest for the mother to be happily oblivious to the fact that she's pregnant.

Why? Well, sometimes, the normal stresses of a pregnancy combined with other stresses in a mother's life can lead to miscarriage. But a 'stealth' pregnancy that uses few resources in a mother's body can actually increase the foetus's chance of survival.

Bleeding or continued periods during a cryptic pregnancy

A vast majority of the women who go through a cryptic pregnancy will continue to have some sort of "period-like" bleeding through the entire pregnancy.

Because she will continue to bleed throughout the entire pregnancy, the hCG is never allowed to build up and secrete into the urine or blood, because some of it is shed every time she bleeds.

This is the cause of so many negative pregnancy tests.

Weight gain or weight loss during a cryptic pregnancy

Some women going through a cryptic pregnancy will gain weight gradually - and (depending on the position of the foetus) not necessarily in a neat bump.

Others, due to food aversion, may lose weight during the first few months.

How to confirm a cryptic pregnancy?

Ultrasounds don't tend to pick up cryptic pregnancies, because of the positioning of the baby and/or various other reasons (uterine retroversion, bicornuate uterus).

One way to detect a baby during cryptic pregnancy is by using a Doppler and finger pulse, which picks up and monitors the fetal heart rate. You can arrange this with your GP.

What to do if you think you may be going through a cryptic pregnancy

If you are experiencing some pregnancy symptoms but not others, or even if you just “don’t feel right,” you should make an appointment to see your doctor as soon as possible.
