Increased Breast Size

Very Early Pregnancy Symptom

Symptom Details

The swelling of the breasts in early pregnancy is due to the increase of hormones which cause increased blood flow to the breasts to begin the preparation for breastfeeding. The breasts may increase by a full cup size in just the first 12 weeks of pregnancy.

**NOTE: Data for 15-21 dpo tends to be lower than expected as many women stop tracking symptoms after a positive pregnancy test.
