Swollen or tender breasts can appear as soon as the day your period is due or even earlier. Early pregnancy and pre-menstrual symptoms are very similar, so tender breasts may occur up to a week before your period is due. A pregnancy test will confirm one way or the other as soon as your period is late.
It itself I wouldn't rely on this as a pregnancy symptom. Breast tenderness does occur during pregnancy but it also occurs when your period is due or have just finished, when your bra is too tight or if pressure is applied to your breasts. Breasts are very sensitive. If your period fails to arrive then perform a pregnancy test.
