PMDD is not just “really bad PMS.”
PMS and PMDD are not simply two names for the same experience. PMDD involves severe cyclical symptoms that can significantly interfere with work, relationships, school and everyday functioning. Timing, severity and impact are important, and tracking symptoms across cycles can help show the pattern.
This is why looking at one symptom in isolation can send you down the wrong rabbit hole. Your cycle timing, how long the change has been happening, whether it repeats and what else changed at the same time all add context.
The goal is not to diagnose yourself from a post. It is to understand your body well enough to recognise a pattern and know what information may be worth taking into a proper health conversation.
Save this for later, and send it to a woman who was never taught this.
