I don't really know... Yes, low estrogen and a surge of progesterone are features of PMS, but I think the effects of PMS depend on a person's total body chemistry. If you already have low serotonin levels in the brain then the hormonal shifting can affect mood. Some people don't experience PMS at all. Lucky them!
