When Do Pregnancy Cravings Start? A Trimester-by-Trimester Guide

June 12, 2026·20 min read

One day you are perfectly normal. The next, you are sending your partner to three different stores at 10 p.m. in search of a very specific brand of pickle. Or you cannot stop thinking about mashed potatoes. Or something you have never particularly enjoyed — cream cheese, orange juice, a fast food item you have not eaten in years — has become the only thing that sounds tolerable.

Pregnancy cravings are one of the most universal, most talked-about, and most genuinely fascinating aspects of pregnancy. They are real. They are often intense. And they arrive with a specificity and urgency that can surprise even women who were expecting them.

If you are searching for when pregnancy cravings start, you are probably either waiting for them, already in the middle of them, or trying to understand what your body is telling you. This guide covers all of it — when cravings typically begin, what causes them, how they change across each trimester, what the most common cravings are, when they are worth paying attention to medically, and how to manage them without derailing your nutrition.

No judgment here. Cravings are part of the experience. Let's make sense of them.

When Do Pregnancy Cravings Start?

The short answer: for most women, pregnancy cravings begin in the first trimester — typically somewhere between weeks 5 and 9.

This timing is not coincidental. It maps almost perfectly onto the period of most dramatic hormonal change in early pregnancy, when hCG (human chorionic gonadotropin) is rising most rapidly and estrogen and progesterone are shifting significantly. These hormonal changes affect the brain's reward and appetite systems in ways that are only beginning to be fully understood by researchers.

Here is a more complete picture of when cravings tend to arrive and evolve:

Weeks 5–9: First cravings often appear, sometimes alongside or intertwined with food aversions. The two frequently occur simultaneously — an intense desire for certain foods paired with an equal and opposite revulsion toward others.

Weeks 10–12: Cravings often intensify as hormones continue to shift. This is frequently the peak of both nausea and cravings, which can make eating feel like a complicated negotiation between what sounds tolerable and what sounds irresistible.

Weeks 13–27 (second trimester): For many women, cravings persist through the second trimester and may become more specific. The nausea that complicated eating in the first trimester has often eased, and appetite returns — sometimes dramatically. Cravings in this window are often the most memorable.

Weeks 28–40 (third trimester): Cravings can continue but often shift in character. Some women report cravings decreasing in intensity; others find new ones emerging. The physical constraints of the third trimester — stomach compression, heartburn — sometimes naturally moderate eating patterns and cravings alongside them.

After birth: Cravings typically resolve within the first few days to weeks postpartum as hormone levels normalise. Some women report specific cravings immediately after delivery — often for foods they avoided during pregnancy.

What Causes Pregnancy Cravings?

The science behind pregnancy cravings is more nuanced than the popular explanation of "your body knows what it needs" — and more interesting.

Hormonal Changes

The most well-supported explanation for pregnancy cravings is hormonal. The dramatic and rapid shifts in hCG, estrogen, and progesterone that characterise early pregnancy affect multiple systems involved in appetite, taste, smell, and reward processing.

hCG — which doubles approximately every 48–72 hours in the first trimester — is associated with both nausea and the changes in taste and smell sensitivity that accompany early pregnancy. The same hormonal surge that makes certain smells unbearable can make certain flavours intensely appealing.

Estrogen affects taste perception directly. Rising estrogen levels alter how the taste buds perceive sweet, salty, sour, and bitter flavours — which may explain why many pregnant women crave very specific flavour profiles, or find that previously enjoyed foods taste different and unappealing.

Progesterone affects the digestive system and appetite regulation. Its sedating and appetite-stimulating effects contribute to the increased hunger many women experience in the second trimester, which can amplify cravings.

Heightened Smell and Taste Sensitivity

Pregnancy dramatically increases olfactory sensitivity — the acuity of the sense of smell. This is one of the most consistent early pregnancy changes and is driven by rising estrogen. The same mechanism that makes certain smells nauseating can make the smell of a particular food intensely appealing, triggering cravings that are almost Pavlovian in their urgency.

Nutritional Needs and Deficiencies

The "your body knows what it needs" explanation is not entirely without merit — but it is frequently overstated. Some specific cravings do appear to correlate with nutritional needs:

Salt cravings can reflect the increased blood volume of pregnancy and the expanded need for sodium and electrolytes.

Red meat cravings are sometimes associated with iron deficiency, which is common in pregnancy.

Citrus cravings may reflect vitamin C needs or a desire for the taste profile that helps manage nausea.

However — and this is important — many pregnancy cravings appear to have no direct nutritional explanation whatsoever. The craving for a specific fast food item, for a childhood comfort food, or for an unusual combination of flavours does not necessarily reflect a deficiency. The brain's reward system is complex, and cravings are influenced by memory, comfort, and emotional associations as much as by physiology.

Emotional and Psychological Factors

Pregnancy is an emotionally intense season. Stress, anxiety, comfort-seeking, and the heightened emotional sensitivity of the first trimester all contribute to the desire for specific foods — particularly comfort foods with strong positive associations. This does not make the craving less real. It simply means the cause is multifactorial rather than purely nutritional.

First Trimester Cravings: Weeks 1–13

The first trimester is when cravings most commonly begin — and when they arrive alongside their complicated companion, nausea. The interplay between the two is one of the stranger experiences of early pregnancy: simultaneously wanting something specific intensely while also feeling too sick to eat much of anything.

What First Trimester Cravings Look Like

First trimester cravings tend to be:

Specific and urgent. Not "I could go for something sweet" but "I need exactly this brand of ginger biscuit right now." The specificity can be startling.

Intertwined with aversions. Many women in the first trimester find that certain smells or foods that were previously neutral become intolerable, while others become intensely appealing. The two often flip simultaneously — foods previously loved becoming revolting, and foods previously uninteresting becoming the only thing that sounds good.

Shifting. First trimester cravings can change week to week or even day to day as hormone levels fluctuate.

Flavour-specific. Sour, salty, and tart flavours are particularly common cravings in the first trimester — perhaps because these flavours stimulate saliva production, which can reduce nausea.

Most Common First Trimester Cravings

Sour and citrus foods — lemon, pickles, citrus fruit
Salty snacks — crisps, pretzels, crackers
Carbohydrate-heavy comfort foods — bread, pasta, potatoes
Cold foods — ice cream, cold fruit, iced drinks
Strong-flavoured or pungent foods

Managing Cravings When Nausea Complicates Everything

The first trimester presents a unique challenge: cravings and nausea coexisting. Practical strategies include:

Eating small amounts frequently to manage both hunger and nausea
Following cravings for plain, bland foods when that is what the body accepts — crackers, toast, plain rice
Using ginger (tea, chews, biscuits) to manage nausea while exploring what sounds tolerable
Trusting that survival eating in the first trimester is appropriate — nutrition perfection is not the goal when nausea is severe

Second Trimester Cravings: Weeks 14–27

The second trimester is widely considered the peak of the pregnancy craving experience — and for good reason. Nausea has typically eased, appetite returns with enthusiasm, and the hormonal environment is producing some of its most pronounced effects on taste and appetite.

What Second Trimester Cravings Look Like

Second trimester cravings are often:

More food-positive. Rather than being intertwined with revulsion and nausea, second trimester cravings tend to be about genuine desire and enjoyment of food.

More specific and memorable. These are often the cravings that become pregnancy stories — the midnight ice cream run, the specific restaurant that had to be visited weekly, the unusual combination that made perfect sense at the time.

More sustained. Rather than shifting rapidly, second trimester cravings can persist for weeks or months.

Larger in appetite. Many women experience a genuine increase in hunger in the second trimester as caloric needs increase and the nausea that suppressed appetite in the first trimester resolves.

Most Common Second Trimester Cravings

Sweet foods — ice cream, chocolate, baked goods, fruit
Savoury and salty combinations
Specific restaurants or fast food
Fruit — particularly cold, juicy fruits
Dairy products — cheese, yoghurt, milk
Red meat — sometimes associated with rising iron demands

The Sweet vs. Savoury Question

Research on pregnancy cravings consistently finds that sweet and savoury (particularly salty) are the two most common craving categories, with sweet somewhat predominating. This reflects the hormonal influence on taste perception — estrogen and progesterone both affect the brain's response to sweet flavours and the reward pathways associated with them.

Many women crave both — the famous combination of sweet and salty (ice cream and crisps, chocolate and salt, sweet-and-sour) reflects the complex flavour profile preferences that pregnancy hormones can produce.

Third Trimester Cravings: Weeks 28–40

The third trimester brings its own craving landscape — shaped by the physical realities of late pregnancy as much as by hormones.

What Third Trimester Cravings Look Like

Modified by physical constraints. The growing uterus compresses the stomach, making large meals uncomfortable and heartburn more pronounced. Many women find that third trimester cravings become more moderate in intensity simply because eating large quantities is physically difficult.

Comfort-focused. As the emotional intensity of approaching birth builds, comfort food cravings often increase — familiar, soothing foods associated with safety and wellbeing.

Carbohydrate and energy-focused. The body's energy demands are highest in the third trimester, and cravings for calorie-dense foods often reflect this.

Sometimes surprising or new. Some women report cravings emerging in the third trimester that were not present earlier — foods they did not want in the first or second trimester that suddenly become appealing.

Managing Cravings in the Third Trimester

The physical constraints of late pregnancy naturally encourage the eating patterns that are actually most beneficial — small, frequent meals rather than large ones. Working with rather than against these constraints is easier on digestion, heartburn, and energy levels.

The Most Common Pregnancy Cravings

Research across multiple studies on pregnancy cravings consistently finds the same categories appearing most frequently:

Sweet foods — ice cream, chocolate, baked goods, candy, and sweet fruits are among the most universally reported pregnancy cravings. Studies suggest 40–50% of pregnant women report sweet cravings.

Savoury and salty foods — crisps, pickles, pretzels, cheese, and salty snacks are widely reported and particularly common in the first trimester.

Spicy foods — a significant proportion of women crave spicy food during pregnancy, despite the heartburn implications.

Dairy — ice cream, cheese, and yoghurt are frequently craved, potentially reflecting calcium and fat needs.

Fruit — cold, sweet, and citrus fruits are among the most commonly reported cravings and are also among the most nutritionally benign to follow.

Carbohydrates — bread, pasta, potatoes, and rice are staple pregnancy cravings, particularly in the nausea-affected first trimester.

Red meat — particularly notable for women with low iron, and one of the more nutritionally meaningful cravings.

Fast food — specific fast food items and restaurants are reported with remarkable frequency and specificity. The combination of salt, fat, and familiar flavour profiles appears to be particularly satisfying to the pregnant palate.

Pica: When Cravings Become a Medical Concern

Most pregnancy cravings are benign — they involve food, they are manageable, and they do not pose health risks when satisfied in reasonable amounts. But there is one category of craving that is a genuine medical concern: pica.

Pica is the craving for and consumption of non-food substances — most commonly:

Ice (pagophagia) — the most common form
Dirt or clay (geophagia)
Chalk
Laundry starch or detergent
Cornstarch
Paint chips
Sand or gravel
Paper

Pica is more common during pregnancy than at other life stages and is strongly associated with iron deficiency anaemia — though not exclusively caused by it. A craving for ice in particular is one of the most consistent signals of low ferritin levels in clinical practice.

If you are craving non-food substances, tell your care provider at your next appointment. It is not something to be embarrassed about — it is a recognised medical phenomenon, and it is worth investigating the underlying nutritional deficiency that is often driving it. It is also worth knowing that consuming many non-food substances carries genuine risks (heavy metals in clay or paint, chemical toxicity in laundry products) that matter in pregnancy.

Pregnancy cravings are your body speaking a language that is part hormonal, part nutritional, and part deeply human. You don't have to understand every word — but the ones worth listening to most carefully are the unusual ones.

Food Aversions: The Other Side of Cravings

Cravings and aversions are two sides of the same hormonal coin, and they frequently arrive together. Understanding aversions helps complete the picture of what is happening in the appetite and taste systems during pregnancy.

The most common pregnancy food aversions include:

Meat and poultry — particularly raw or cooking meat; one of the most reported aversions especially in the first trimester
Eggs — frequently reported, particularly the smell of cooking eggs
Coffee — the smell becomes intolerable for many women in early pregnancy
Alcohol — many women report a complete aversion to alcohol smell and taste in early pregnancy
Spicy foods — sometimes craved, sometimes strongly avoided, depending on the individual
Garlic and onions — strong cooking smells commonly become aversive

Aversions, like cravings, are driven by the same hormonal and sensory changes of pregnancy and tend to follow a similar timeline — peaking in the first trimester and often easing in the second.

When to Follow Your Cravings and When to Be Thoughtful

Not all cravings are equal in their nutritional implications. Here is a practical framework:

Follow freely:

Fruit and fruit juices (within reason on sugar)
Dairy products — yoghurt, cheese, milk
Lean protein cravings — meat, fish, eggs, legumes
Vegetables in any form
Whole grains and complex carbohydrates

Satisfy in moderation:

Ice cream and sweet treats — enjoy without guilt, but not as the primary food group
Salty snacks — sodium needs are higher in pregnancy, but extremely high salt intake affects blood pressure
Fast food — satisfying a craving occasionally is fine; daily as the primary diet is worth reconsidering
Spicy food — safe for the baby, but can intensify heartburn in the third trimester

Be cautious with:

Very high sugar intake — relevant to gestational diabetes risk
Raw fish or meat — unsafe regardless of how strong the craving is
High-mercury fish (shark, swordfish, bigeye tuna) — avoid even if craved
Alcohol — no safe amount in pregnancy; the craving for a glass of wine is understandable and worth acknowledging, but not acting on
Non-food substances — see pica section above

The overall principle: the intensity of a craving does not determine whether satisfying it is safe or wise. Some cravings are worth following; some are worth redirecting. A strong craving for something that is genuinely unsafe during pregnancy does not make that thing safe.

Frequently Asked Questions

When do pregnancy cravings start?

Most women notice the first pregnancy cravings between weeks 5 and 9 of pregnancy, coinciding with the period of most rapid hormonal change. Some women notice cravings even earlier; others do not experience noticeable cravings until the second trimester. The timing varies between women and between pregnancies.

Do pregnancy cravings mean anything?

Sometimes — but not always as literally as the "your body knows what it needs" explanation suggests. Cravings for red meat may reflect iron needs. Cravings for dairy may reflect calcium needs. Cravings for salty foods may reflect increased electrolyte demands. However, many cravings — particularly for specific comfort foods or fast food items — reflect hormonal effects on the brain's reward system, emotional factors, and taste perception changes rather than specific nutritional deficiencies.

When do pregnancy cravings peak?

For most women, cravings are most intense in the first trimester (weeks 5–12) when hormonal changes are most dramatic, and again in the second trimester when nausea has eased and appetite returns fully. Third trimester cravings often moderate somewhat due to physical constraints on eating.

When do pregnancy cravings stop?

Most pregnancy cravings resolve within days to weeks after birth as hormone levels normalise. Some women notice a marked shift in food preferences immediately postpartum. During pregnancy, cravings may ease somewhat in the third trimester but typically continue throughout.

Do pregnancy cravings predict the baby's sex?

This is one of the most persistent pregnancy myths — and the evidence does not support it reliably. The popular belief that sweet cravings predict a girl and savoury cravings predict a boy has been studied and not found to be a reliable predictor. Sweet cravings are the most common craving category regardless of fetal sex.

Is it normal to crave non-food items during pregnancy?

Craving non-food items — ice, dirt, chalk, laundry starch — is called pica and is more common during pregnancy than at other times. It is strongly associated with iron deficiency anaemia. If you are craving non-food substances, mention it to your care provider, as it warrants investigation of your iron levels and other nutritional status. Do not consume non-food substances during pregnancy.

Why do I crave sour foods during pregnancy?

Sour and tart flavours are among the most commonly craved in pregnancy, particularly in the first trimester. Possible explanations include the stimulating effect of sour flavours on saliva production (which can ease nausea), hormonal changes in taste perception, and the brain's association of tart flavours with fresh, safe food. Lemon, pickles, citrus, and vinegary foods are all reported frequently.

What if I am craving things I should not eat during pregnancy?

A craving for something unsafe — alcohol, raw fish, high-mercury seafood — does not make that thing safe to consume during pregnancy. Acknowledge the craving without acting on it, find the closest safe alternative (a mocktail instead of wine, cooked sushi instead of raw, canned light tuna instead of swordfish), and speak with your care provider if cravings for unsafe items are persistent or distressing.

Conclusion: Your Cravings Are Part of the Story

Pregnancy cravings are one of the most human parts of this experience — specific, surprising, sometimes hilarious, and deeply memorable. The midnight pickle run. The inexplicable devotion to a particular flavour. The foods that became synonymous with this particular pregnancy and this particular season of your life.

They are driven by biology, shaped by emotion, and experienced differently by every woman who goes through them. Most of them are benign. Most of them are worth following — with a little thought about frequency and alternatives for the less nutritious ones. And almost all of them will make excellent stories later.

If your cravings are intense, know that they are real and they are normal. If they are absent, know that is equally normal. If they involve non-food substances, know that your care provider wants to hear about that.

And if someone sends you to three stores at 10 p.m. for a specific brand of pickle — well. That is just part of the journey. You are growing a person. A little pickle is the least of it.
