I feel like a different person for a week before my period. Is that real?

An AskHer answer: what is known, what depends on you, and what only a clinician can decide.

Nobody asked this one. AskHer’s editorial team wrote the question to open the topic. It is not anyone’s submission, and nobody’s own words are in it.

Editorially reviewed Version 1 · Last reviewed 25 September 2026 · English

The short explanation

It is, it has a name, and there is treatment. Marked mood change confined to the two weeks before a period and lifting once it starts is premenstrual dysphoric disorder when it is severe, and premenstrual syndrome when it is milder. The pattern — tied to the cycle, and clearing afterwards — is what distinguishes it from depression running underneath. Keeping a note across two or three cycles is what makes a diagnosis possible.

What depends on your situation

The parts of this that change from woman to woman. Uncertainty is stated, not hidden.

  • Treatment options range from cycle-tracking and lifestyle measures to SSRIs, which can sometimes be taken only in the luteal phase, and to hormonal approaches. Which suits depends on severity, whether you want contraception, and what else you are managing.

What this answer cannot determine

The boundary of online education. These need a clinician who can see you.

  • This cannot diagnose you, and it cannot distinguish a premenstrual disorder from depression that worsens premenstrually — a distinction that changes the treatment, and one a diary resolves better than a conversation from memory.

Questions for your clinician

Take these with you. You can add any of them to an appointment card.

  1. Should I track symptoms across a few cycles first?
  2. Is this premenstrual, or something underlying that gets worse?
  3. What are the treatment options and their side effects?
  4. Would contraception help or make it worse?

When to seek help

Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.

  • Get help the same day for thoughts of ending your life. Suicidal thoughts that cluster premenstrually are recognised and are treated urgently rather than waited out.

“Explain more simply” asks you which part was hard to follow, so the author knows what to rewrite. “My question is different” opens a private follow-up with this answer attached.
