No.: Birth control pills are known to slightly increase the size of ones breast. Also, weight gain can increase the overall size. Please mention this at your follow up visit.

Not strange: The oral contraceptive pill contains a very small amount of estrogen which can stimulate breast growth. The more likely cause of breast growth is weight gain which will add fat to the ducts and glandular materiel in the breasts.
