Not entirely clear: But changing hormone levels can lead to changing bowel patterns. Prostaglandins which increase during your period cause the uterus to contract. Prostaglandins can also act on your gut.

Prostaglandins: Prostaglandins are chemicals secreted by your body that cause your uterus to contract when you have your period. They are also responsible for bowel contraction - leading to increase in stooling. The hormonal changes that occur around the time of your period also can be responsible for changes in bowel patterns. Let your friend know that what she is experiencing is normal.
