Premenstrual syndrome, more commonly known as PMS, is a combination of physical and emotional symptoms that menstruating people experience after ovulation and before the start of their period.

Research shows that up to 90 percent of menstruating people experience PMS symptoms from time to time, making it a common issue. While the cause of PMS is unclear, researchers believe it’s related to the changing hormone levels of the menstrual cycle.

Symptoms of PMS

Many menstruating people experience painful and inconvenient symptoms before the start of their period.

You probably remember the somewhat awkward stage in life called puberty. Puberty marks the beginning of the transition from childhood to adulthood. Puberty is accompanied by many physical and emotional changes. While each girl may experience puberty differently, learning about each stage and the changes they bring can help you support your child and navigate the stages of puberty together.

Puberty happens due to changes in the hormone levels in a person’s body.
