PMS as an actual syndrome only really affects somewhere between 3 and 30% of women, although as much as 80% of women experience some of the symptoms at various reduced levels regularly.* and most women will experience at least some of the symptoms occasionally.
*In this case, PMS is only PMS if it actually significantly interferes with your normal activities: i.e. cramps bad enough that you can't walk or drive, headaches that would meet clinical definitions of migraines, real anxiety attacks, etc.
