Food cravings during pregnancy

By trimester

Weeks 1–13

1st trimester

Cravings often start early and lean toward sweet, salty, or sour foods, sometimes tangled up with nausea. If you notice yourself wanting to chew ice constantly, mention it at your first prenatal visit since it can be an early clue about your iron levels.

Weeks 14–27

2nd trimester

Routine bloodwork around this time usually checks for anemia, which is a good moment to bring up any ice or non-food cravings you've noticed. Ordinary food cravings, meanwhile, are still completely normal and don't need any special action.

Weeks 28–birth

3rd trimester

Cravings tend to fade for many women by now, but your iron needs stay high as your blood volume keeps expanding. A new or strong urge to chew ice or eat something like chalk or dirt is worth a call to your provider rather than waiting for your next visit.

What does the evidence show for food cravings?

• About 4 in 10 pregnant women get food cravings, usually for sweets, fruit, or dairy, and satisfying them hasn't been linked to extra weight gain or blood sugar problems once total calories are accounted for. 1
• Cravings and food aversions are both extremely common in pregnancy, showing up in well over half of women, but cravings don't follow the same timeline as morning sickness the way aversions often do. 2
• An unusual pull toward non-food items like ice, chalk, or dirt, sometimes called pica, is common enough worldwide to show up in roughly a quarter of studied pregnancies, and it tends to run higher wherever anemia is more common. 3
• Iron needs roughly double during pregnancy to 27 milligrams a day, and routine prenatal blood work checks for anemia so your provider can recommend extra iron if your levels run low. 4
• Iron-deficiency anemia that goes unaddressed in pregnancy raises the risk of premature birth and low birthweight, which is the real reason a new craving for ice or something inedible is worth mentioning at your next visit. 5
• Pica, an urge to eat non-food items like ice, dirt, or clay, is linked to iron-deficiency anemia and carries its own risks: clay and dirt can carry parasites like Toxocara and Ascaris, lead exposure can cause severe headache or seizures, and swallowing large amounts of non-food material can lead to a bowel blockage that requires surgery. 6

When should I call my provider about food cravings?

A pull toward eating ice, dirt, clay, chalk, or other non-food items (pica) is the specific craving pattern worth reporting, since it's tied to iron-deficiency anemia and carries its own risks: clay and dirt can carry parasites, and swallowing large amounts of any non-food material can lead to a blockage that needs surgery. Mention pica at your next visit if it's mild and occasional, but call sooner if it comes with belly pain or vomiting, which can point to that kind of blockage. A severe headache or a seizure alongside pica needs emergency care, since either can be a sign of lead exposure from dirt or clay. Trust your read on your own body. If something feels off beyond the list above, please consult your healthcare provider rather than waiting it out.
