PMDD & Cycle Education
Understanding PMDD and Cyclic Mood Changes
If your anxiety, mood or energy shifts follow a monthly pattern, then this is a clear sign it is cycle-related.
After ovulation, progesterone, blood sugar stability and nervous system reactivity shift together. For some women, this creates predictable symptoms.
Explore the physiology behind these patterns below.
This is where the physiology actually lives. Each shift below- hormonal, metabolic, immune, neurological- plays its own part in why the two weeks before your period can feel so different from the rest of the month. None works in isolation, and none is a character flaw.
Start with whichever one matches what you're noticing, or work through them in order to build the full picture.
