One finding has continued to stand out in PMDD research.
In a 2022 study from Monash University, 83% of women with PMDD reported experiencing early life trauma, with emotional abuse being the most commonly reported form (71%). These numbers are striking, but they do not mean that trauma causes PMDD. Many people develop PMDD without any history of trauma.
What the findings do suggest is that, for a substantial proportion of women, trauma and PMDD exist alongside each other. Understanding that relationship may help explain why the luteal phase can feel especially overwhelming for those living with both PMDD and trauma. For those affected by both, the question may not simply be why PMDD symptoms become more intense, but why the past itself can sometimes feel much closer during the luteal phase.
When hormones meet a sensitised nervous system
PMDD is increasingly understood as a neurobiological condition in which the brain responds differently to the normal hormonal changes of the menstrual cycle. During the luteal phase, brain systems involved in emotional processing, stress responses and threat detection become more sensitive, while the networks responsible for regulating those responses may become less effective.
Trauma can leave lasting changes in how the brain responds to stress and potential danger. The nervous system learns to detect threat more quickly because, at one point in life, being highly alert may have been necessary for survival.
When these two processes overlap, the result can be a nervous system that reacts with far greater intensity than the situation itself would seem to justify. A disagreement may feel devastating. A stressful email may feel impossible to cope with. Feelings of rejection, shame or fear can arrive with remarkable speed and intensity, even when another part of you knows that you are safe.
When the past suddenly feels close again
Living with both PMDD and trauma can sometimes make the luteal phase feel as though old wounds suddenly become much easier to access. Memories, emotions or survival responses that usually remain in the background may come much closer to the surface.
Some describe this as emotional flashbacks, or even trauma flashbacks, although this experience has not yet been well studied.
These are not always visual memories. Sometimes they are emotional or physical experiences: an overwhelming sense of fear, shame, helplessness or abandonment that seems to appear without warning. The body reacts as though something dangerous is happening in the present, even when the mind knows it is not.
Whether these experiences represent true trauma flashbacks or a heightened activation of the nervous system is not yet fully understood. However, those living with both PMDD and a history of trauma often describe feeling as though the distance between the present and the past becomes much smaller during the luteal phase. Recognising this pattern can be deeply validating. It shifts the question from "Why am I falling apart again?" to "What is my nervous system trying to tell me?"
Understanding can change how we respond
If you live with both PMDD and trauma, you do not have to choose which one is "real." Both can shape your experience, and both deserve care.
Understanding what your nervous system has been through does not change the past, but it can change how you relate to yourself in the present. The goal is not to judge yourself for reacting this way, but to recognise that there are understandable reasons why certain times of the month feel so much harder than others.
Healing rarely begins with self-criticism. More often, it begins with understanding, self-compassion and the knowledge that your nervous system is doing its best with the experiences it has carried.
