PMS... You’ve probably heard of (premenstrual syndrome) by now. What is PMS?
Symptoms appear before your period starts (as many as five days) and will disappear during your period. Symptoms can affect your body and your brain, and their intensity can vary a lot from girl to girl. (As if you don’t have enough to deal with.)
The bad news is that no one really knows the exact reason. What doctors and scientists do know is that it’s related to the way your body’s hormones change through your monthly cycle.
The Mayo Clinic estimates about 75 percent of women get at least some form of premenstrual syndrome or PMS. So if you have PMS, one thing’s for sure – you’re not alone! Although not every girl gets them, PMS symptoms can actually last through your period, too. If you don’t get them, consider yourself lucky.
