Slight pains contained by my breasts?

I'm pretty sure my breasts have grown to their potential.. so It's not growing.. and I regularly check for breast cancer and it doesn't run within my family.. so I really doubt it's that. It feel like it's coming from my nipple or from the center of the breast. Could it be a sign of pregnancy? What else could it be besides that because I don't want to really consider it's because of pregnancy.Slight pains contained by my breasts?
Breast Tenderness is a sign of pregnancy but it may also be due to hormones. I suggest a pregnancy test.
it could be pregnancy, your term or just something to do next to your hormones. if it's really painful or doesn't progress away soon you should see a doctor
Certain times during your monthly hormonal cycle can do that, if there's a pattern, it could be that.
It's probably simply the breast pain that comes near your period. Also, don't be so express to assume that your breasts are done growing- I don't know your age, but breast development usually continues into a person's 20s (and sometimes even into their 30s).
