Before I start my period I get aches in my breasts. This happens every time. Will it go away when my breasts finish developing? And will wearing a more supportive bra help?
– Simone*

Lots of girls get aching in their breasts before their periods start. The aches are caused by changes in the hormones estrogen and progesterone, which are responsible for a girl's menstrual cycle.

For some girls, these aches are less frequent as they grow older. But that's not the case for everyone — some women continue to get aches in their breasts for as long as they have their periods.

So what can you do? Cutting back on salt and caffeine may help. Wearing a supportive bra during this time may make you more comfortable. And taking an over-the-counter pain reliever can help reduce pain.

Regular exercise may also help lessen menstrual breast pain. Obviously, certain types of exercise (like running) may make things worse during the time when your breasts are hurting. So on those days, stick with an exercise that is lower impact, such as biking.
