normally after puberty and when your pregnant
When you're pregnant, the milk isn't in your breasts yet. It's not until after you actually give birth that you get milk in your breasts. It follows colostrom, which is a natural antibiotic.
This all depends on your age. In women, breasts can grow until they are 18, sometimes older! If you are concerned you are pregnant, you will know because not only will your breasts get larger, but they will hurt tremendously!
No. Just because your breasts are sore doesn't mean that you are pregnant. When you get your period, your breasts tend to get sore too. Sore breasts aren't the only sign of pregnancy.
Well your breasts will grow for a while. When you gain weight, start birth control, or become pregnant your breasts will increase in size. But once you are pretty much done with puberty your breasts won't continue to grow on there own, buy only from another independent factor.
Both the times I was pregnant my breasts were swollen but not sore right away but only a pregnancy test will tell you for sure.
