Cravings can start as early as the first trimester for many people, but the timing is quite individual. Here’s a concise overview:

• Typical onset: end of the first trimester (around 12 weeks) to the second trimester, with many people noticing stronger cravings as pregnancy progresses into weeks 13–26. Some people may experience cravings as early as 5–6 weeks, while others may not have noticeable cravings at all.

• Factors involved: hormonal changes (notably hCG and progesterone), mood and stress, and nutritional needs can all influence when cravings begin and what they are. Cravings can also shift or persist throughout pregnancy for some individuals.

• Variability by individual: cravings vary widely in type (savory, sweet, or specific textures) and duration; there’s no single “normal” pattern that fits everyone. If cravings are overwhelming or accompanied by other concerning symptoms, it can help to discuss with a prenatal care provider.

Direct answer: For most people, pregnancy cravings tend to begin in the first trimester or by the end of it, often intensifying in the second trimester, but they can start as early as around 5 weeks or be delayed for some individuals. If you’re newly pregnant and curious about your own experience, monitor how you feel over the next few weeks and speak with a healthcare provider if cravings are persistent, unusual, or associated with other symptoms.
