Pregnancy cravings often start sometime in the first trimester, typically between about 5–12 weeks of pregnancy, but the exact timing varies a lot from person to person. Some people notice cravings as early as a few weeks after conception, while others do not get strong cravings until the second trimester—or may not experience them at all.

Typical start window

  • Many sources describe cravings starting in the first trimester , sometimes as early as around the fifth week of pregnancy.
  • Some people report very early cravings within a few weeks of conception, though this is not universal.
  • For those who do get cravings, they often get more noticeable in the second trimester and then fade by the third trimester.

Why cravings start

  • Hormonal shifts in early pregnancy (including rising hCG and changes in other hormones) are thought to affect appetite, taste, and smell, which can trigger new likes and dislikes for certain foods.
  • Changes in the brain’s reward and energy‑balance centers during pregnancy may also play a role in driving specific food cravings.

What’s “normal” vs. concerning

  • It is normal for:
    • Cravings to start anytime in the first or early second trimester
    • Cravings to change over time or disappear suddenly
    • To have no clear cravings at all and still have a healthy pregnancy
  • Talk with a healthcare professional promptly if:
    • You crave non‑food items (like dirt, ice, paper, or chalk), known as pica
    • Cravings lead you to skip balanced meals or cause rapid, excessive weight gain or weight loss

Practical tips for early cravings

  • Pair “fun” foods with something nutritious (e.g., salty crackers with cheese, chocolate with a handful of nuts) to help keep blood sugar steadier.
  • Eat small, frequent meals or snacks if nausea and cravings arrive together; this can make both more manageable.
  • Keep your provider updated on strong or unusual cravings so they can check nutrition, weight gain, and any possible deficiencies.

Bottom line: Pregnancy cravings can start surprisingly early—often around week 5–12—but there is a wide “normal” range, and having no cravings at all can also be completely normal.
