📅 When It Occurs
Begins as early as 1-2 weeks after conception, continues throughout pregnancy
📊 How Common
Affects 75-90% of pregnant women
Overview
Breast changes are often one of the first noticeable signs of pregnancy. Your breasts may feel tender, heavy, and fuller, similar to how they feel before your period but more intense.
These changes are your body's way of preparing to nourish your baby. Your milk ducts are expanding, blood flow is increasing, and fatty tissue is building up. By the end of pregnancy, your breasts may be a full cup size or two larger.
While tender and sometimes uncomfortable, these changes are completely normal and indicate your body is responding appropriately to pregnancy hormones.
