    Boobs don't grow just during periods, they grow all the time when you start puberty and will finish from the ages of 17-19

    They will grow in their own time :3

    Your boobs grow wheather your on your period or not. They can swell and got sore a few weeks or days before your period starts though.

    Very normal yes...hormones can cause cystic like lumps..and they can become painful before and/or during your period. Greasy foods, any type of caffiene (chocolate too) and too much salt can make your breasts more tender during this time. Of course if you are still concerned ask a school nurse or have parent call your family doctor.
